Answer:
3 x 4 + 44 x 3 + 139 x 2 − 168 x + 88 /x + 8
Step-by-step explanation:
f(x) = 2x - 3 and f(x) = f'(x), find the value of x.
Answer:
x=1
Step-by-step explanation:
According to your typed question,
f(x)=2x-3
Let f(x)=y
y=2x-3
Now,
Interchanging the positions of x and y
x=2y-3
x+3=2y
x+3/2=y
f'(x)=x+3/2
Then,
f(x)=f'(x)
2x-3=x+3/2
2(2x-3)=x+3
4x-3=x+3
4x-x=3+3
3x=3
x=3/3
x=1
According to your image question,
f(x)=x/2x-3
f(x)=f'(x)
Now,
Let y=f(x)
y=x/2x-3
y(2x-3)=x
2xy-3=x
2xy-x=3
x(2y-1)=3
2y-1=3x
2y=3x+1
y=3x+1/2
f'(x)=3x+1/2
Then,
f(x)=f'(x)
x/2x-3=3x+1/2
2x=6xsq+2x-9x+3
2x=6xsq+7x+3
solve for x ok
A box has a square base with each side measuring 8 inches. The height of the box is 4 inches. What is the surface area of the box in cubic inches?
Answer:
The surface area should be 256 cubic inches
Step-by-step explanation:
The equation you use to find surface area is A=(wl+hl+hw)*2. The w stands for width (8) the l stands for length (8) and the h stands for height (4). When we put these numbers into the equation we get A=(8·8+4·8+4·8)*2. We do the multiplication first, then we add all of them up and times by 2; this gives us our answer of 256.

A tree house has a rectangular floor with a perimeter of 246 inches and a length of 48 inches.
What is the width of the floor?
Answer:
75 inches
Step-by-step explanation:
First, the perimeter of a rectangle is 2(length)+2(width). The length and total of the perimeter was given to us, so the equation looks like 2(48)+2(w)=246
96+2w=246 (multiply and add where you can on both sides)
2w=150 (get all of the variables on one side and the numbers on the other)
w=75 (simplify to get your final answer)
width is 75 inches. [make sure to add the units!]

Solve for unknown values.
X= degrees
Y= degrees
Answer:
X = 85°
Y = 45°
Step-by-step explanation:
95° + x = 180° [angles on a straight line]
x = 180° - 95°
x = 85°
50° + x + y = 180° [sum of angles in a triangle]
50° + 85° + y = 180°
135° + y = 180°
y = 180° - 135°
y = 45°
For an art project, you are using a piece of cloth that is cut out in the shape of a right triangle. Find the area of the cloth. A triangle with side lengths 6 inches, 6 inches, and 8.5 inches.
Answer:
[tex]A=17.99\ in^2[/tex]
Step-by-step explanation:
Given that,
A triangle with side lengths 6 inches, 6 inches, and 8.5 inches.
We need to find the area of the cloth.
The side lengths form an isosceles triangle. The formula for the area of the isosceles triangle is given by :
[tex]A=\dfrac{1}{2}\times b\times h[/tex]
Where
[tex]h=\sqrt{a^2-\dfrac{b^2}{4}}[/tex]
So,
[tex]A=\dfrac{1}{2}\times b\times \sqrt{a^2-\dfrac{b^2}{4}}[/tex]
Put a = 6 and b = 8.5
So,
[tex]A=\dfrac{1}{2}\times 8.5\times \sqrt{6^2-\dfrac{8.5^2}{4}}\\\\A=17.99\ in^2[/tex]
So, the area of the cloth is equal to [tex]17.99\ in^2[/tex].
Barium sulfate, BaSO4, is a white crystalline solid that is insoluble in water. It is used by doctors to diagnose problems with the digestive system. Barium hydroxide, Ba(OH)2, is also a white crystalline solid and is used in wastewater treatment.

help por favor and ill love you forever <33
Answer:
B
Step-by-step explanation:
the second option!
Answer:
It would be 360/n
Step-by-step explanation:
Every shape's exterior angles must combine to form a 360* shape (meaning "full-circle" even though they are not circles). So you must divide 360 by the number of angles a shape has.
Ex #1: A Square has four angles, so the equation to finding the degrees of each exterior angle is 360/4, which equals 90. So 90* per exterior angle.
Ex #2: A Decagon has 10 angles, so the equation to finding the degrees of each exterior angle is 360/10, which equals 36. So 36* per exterior angle.
please help and fast!
i put the image of the question, PLS HELP
Answer:
A translation is when you move in a direction but the shape doesn't turn or change.
You translate an image by moving a shape in any direction without turning it for example: *draw a shape* then move it to anywhere but don't turn the shape.
An easy way of finding the new coordinates is just by looking to which respect it's too. For example when you do a respect to the y axis you keep the second number in the coordinate pair and change the first number's sign in the coordinate pair same to the x axis.
It depends on their sign. Change in x-coordinate. Change in y-coordinate. Right. Increases. No Change. Left. Decreases. No Change. Up. No Change. Increases. Down. No Change. Decreases .
We use vectors to represent a translation. Which means we need direction (up, down, left, or right) and magnitude (length of units).
Find the measure of angle B
Answer:
64°
Step-by-step explanation:
Angles in a straight line add up to 180° so 180° - 116° = 64°

Step-by-step explanation:
company that manufactures a popular multivitamin wanted to determine whether their multivitamin had any side effects. For its initial study, the company chose 2000 individuals to take one of their multivitamin tablets per day for one year. Scientists from the company surveyed the participants to determine whether they had experienced any side effects. The greatest problem with this procedure is that A) only one brand of vitamin was tested B) the study lasted only one year C) the sample size was not large enough D) no control group was used
Answer:
Option D
Step-by-step explanation:
In this experiment, It would have been scientific to compare the result of the experiment on the experimental group(taking the multivitamin) with the control group (Taking no medicine)
Without a control group, a defined impact of multivitamin over the experimental group cannot be deduced.
Hence, option D is correct

Help, please! I will try to give you Brainliest when you get it right.
Step-by-step explanation:
a) x + 14 + 3x = 90b) <1 = 33°<2 = 57°As,
x + 14 + 3x = 90 [Complementary Angles]
=> 4x = 90 - 14
=> 4x = 76
[tex] = > x = \frac{76}{4} [/tex]
=> x = 19
Hence,
<1 = x + 14°
= 19 + 14 = 33°
<2 = 3x
= 3 × 19° = 57°

Answer:
x = 20
Step-by-step explanation:
These angles are equal to each other because they are vertical angles.
Hence, we can equal the two measurements together to solve for x:
3x + 50 = 6x - 10
3x + 60 = 6x
60 = 3x
20 = x
Check your work:
3(20) + 50 = 6(20) - 10
60 + 50 = 120 - 10
110 = 110
Correct
