Answer:
(a+b)^2+(a-b)^2=2(a^2+b^2)
expanding:
a² + 2ab + b² + a² -2ab + b² = 2a² + 2b²
2a² + 2b² = 2a² + 2b²

need by midnight pretty simple i just don't know how to explain it.
Answer:
Side x is adjacent to 30° angle.
Correct method is:
cos 30° = x/15 ⇒ x = 15*cos 30° ⇒ x = 12.99Diego is correct and Steven is wrong.
when finding sine consider the opposite side to the angle, not hypotenusewhen finding cosine consider adjacent side to the angle, not hypotenuseTwo dice are rolled one after another. Construct a sample space and determine the probability that the sum of the dots on the dice total a number greater than 9 if the second die is a 5. The probability that the sum of the dots on the dice is a number greater than 9 if the second die is a 5 is nothing.

An isosceles triangle has base angles that each measure 39 °. Which equation can be used to fi nd t, the measure of the third angle of this isosceles triangle in degrees?
Answer: 102°
Step-by-step explanation:
First and foremost, we should note that an isosceles triangle has two sides that are equal and that the sum of angles in a triangle equals to 180°.
Since we are told that the isosceles triangle has base angles that each measure 39°, the third angle will be:
t + 39° + 39° = 180°
t + 78° = 180°
t = 180° - 78°
t = 102°
The third angle is 102°.

C.
y= −5/4x
Answer:
C.
y= −5/4x
Step-by-step explanation:
Write an equation of the direct variation that includes the given point. (-8, 10)
1
first divide y by x to find the constant
2
Then write the equation using that constant. The constant can be written as a fraction or a decimal.

A snowcone with a radius of 4 cm is sold in a cone-shaped paper cup with a height of 12 cm and an opening 6 cm wide. If all the ice melted in the cup, would it overow?
If the ice melt in the cone shaped cup, it won't overow because the volume of the cone shaped cup is greater than the volume of the snowcone ice.
The snowcone is a sphere.
Volume of a spherevolume = 4 / 3πr³
where
r = radiusTherefore,
volume of the snowcone = 4 / 3 × π × 4³
volume of the snowcone = 256 π/ 3 = 85.33π
Therefore, the volume of the cone canbe found as follows:
volume of the cone shaped paper = 1 / 3 πr²h
h = 12 cm
r = 6cm
volume of the cone shaped paper = 1 / 3 × π × 6² × 12
volume of the cone shaped paper = 144π
Therefore, let find if the ice melt in the cone whether it will overow.
144π - 85.33π = 58.67π
Therefore, the volume of the cone shaped paper is greater than the volume of the snowcone ice . This means that if the ice melt in the cup , it won't overow.

Select all of the true statements. A. 3 gallons = 18 pints B. 5 quarts = 20 cups C. 6 gallons = 30 quarts D. 2 pints = 32 fluid ounces E. 8 pints = 24 cups
Answer:
b
d
Step-by-step explanation:
1 gallon = 8 pint
3 x 8 = 24 pints
the first option is wrong
1 quart = 4 cups
5 x 4 = 20 cups
the second option is correct
1 gallon = 4 quarts
6 x 4 = 24
the third option is wrong
1 pint = 16 ounces
2 x 16 = 32 ounces
the fourth option is correct
1 pint = 2 cups
8 x 2 = 16 cups
the fifth option is wrong

Help what is the answer ?? What is the is the translation coordinate
Answer: (x - 3, y - 6) or S(-5 -3, 6 -6)
First we have to figure out how many spaces left to right (x-axis) and how many spaces up and down (y-axis) will get us to S'
x-axis: -5 - 3 = -8
y-axis: 6 - 6 = 0
Now we just add this to the original coordinate to give us the translation coordinate:
S(-5, 6) → S(-5 -3, 6 -6)
Danielle's pool table is 5 feet wide and 8 feet long. Danielle wants to replace the felt on
the pool table. The felt costs $2.20 per square foot. How much would it cost in total to
replace the felt on the pool table?
Answer:
$88
Step-by-step explanation:
cost to replace the felt = Area of a rectangle x felt cost per square foot
Area = length x width
5 x 8 = 40
cost of replacement = 40 x 2.2 = 88
A number is 11 less than 3 times another number. The sum of the numbers
is 25. What are the two numbers?
Can you please send the work too
Step-by-step explanation:
this is simple use it and enjoy
Step-by-step explanation:
Let x be the first number
Let y be the 2nd number
given,
[tex]x = 3y - 11 \\ x - 3y = - 11[/tex]
as equation 1
and
[tex]x + y = 25[/tex]
as equation 2.
Now we will use elimination method to solve for simultaneous equations.
We will use equation 1 - equation 2 to eliminate x to solve for y.
[tex]x - x - 3y - y = - 11 - 25 \\ - 4y = - 36 \\ y = - 36 \div - 4 \\ = 9[/tex]
Substitute y into equation 2.
[tex]x + 9 = 25 \\ x = 25 - 9 \\ = 16[/tex]
The numbers are 9 and 16.

what connections can you make between polynomial equations and roots of a graph
Answer:
Factors of a polynomial, when set equal to zero and solved, become the zeros of a polynomial.
The zeros of a polynomial are the numbers where the y-values are 0 which means the point will lie on the x-axis.
Zeros and solutions are the same things. It is where the graph will cross the x-axis which means the y-value is zero.
