what is the value of x (x+2)(x-3)=0
Answer:
x = 3 or x = -2
Step-by-step explanation:
Solve for x over the real numbers:
(x + 2) (x - 3) = 0
Hint: | Find the roots of each term in the product separately.
Split into two equations:
x - 3 = 0 or x + 2 = 0
Hint: | Look at the first equation: Solve for x.
Add 3 to both sides:
x = 3 or x + 2 = 0
Hint: | Look at the second equation: Solve for x.
Subtract 2 from both sides:
Answer: x = 3 or x = -2
how is the graph misleading?
Answer:
This graph is misleading because the colours of them are different.

What is the range of the data? 2,8,7,8,6,15,6,3,8
Answer:
13
Step-by-step explanation:
The range of a data set is the difference between the greatest and least values in the set. In this case, the greatest value is 15 and the least value is 2 so the range is 15 - 2 = 13.

Step-by-step explanation:
ACBM is a segment of a circle such
that CM is the perpendicular bisector of AB.
If ICM 4 cm and IABI= 16 cm, calculate:
a the radius of the circle of which ACBM is a
segment
b the angle that chord AB subtends at the
centre of the circle
c the area of the segment.
Answer:
a. 8.94 cm b. 127° c. 12.37 cm²
Step-by-step explanation:
a. Since CM = 4 cm is the perpendicular bisector of AB = 16 cm and r is the radius off the circle. From Pythagoras' theorem,
r² = (AB/2)² + CM²
r = √[(AB/2)² + CM²]
Substituting the values of the variables into r, we have
r = √[(16/2)² + 4²]
r = √[8² + 4²]
r = 4√[2² + 1²]
r = 4√[4 + 1]
r = 4√5 cm
r = 8.94 cm
b. We know that the length of a chord L = 2rsin(θ/2) where r is the radius of the circle, and θ is the angle subtended by the chord AB.
Since L = 2rsin(θ/2) and L = AB = 16 cm,
L/2r = sin(θ/2)
taking sine inverse of both sides, we have
θ/2 = sin⁻¹(L/2r)
multiplying both sides by 2, we have
θ = 2sin⁻¹(L/2r)
substituting the values of the variables, we have
θ = 2sin⁻¹[16/(2 × 8.94)]
θ = 2sin⁻¹[16/17.88]
θ = 2sin⁻¹[0.8949]
θ = 2 × 63.49°
θ = 126.98°
θ ≅ 127°
c. The area of a segment A is given by
A = (θπ/360 - sinθ)r²/2 where θ is the angle subtended by the segment and r = radius of the circle
since θ ≅ 127° and r = 4√5 cm, substituting these values into A, we have
A = (127°π/360 - sin127°)(4√5)²/2
A = (398.93/360 - 0.7988)40
A = (1.1081 - 0.7988)40
A = 0.3093 × 40
A = 12.372 cm²
A ≅ 12.37 cm²

Step-by-step explanation:
Is 8 a solution to -2(x + 10) + 4 = -32? True or False
Step-by-step explanation:
-2(x + 10) + 4 = -32
-2(x + 10) = -32 -4
-2(x + 10) = - 36
x + 10 = (-36)/(-2)
x + 10 = 18
x = 18 - 10
x = 8
8 is a solution ... true
9. If DF = 42, find DE.
7x+1 4x-3
DEF what is DE
Answer:
29
Step-by-step explanation:
So DF = 42, And we know that DF = DE + EF
Therefore (7x+1) + (4x-3) = 42
11x -2 = 42
11x = 44
x = 4
Substitute x = 4 onto DE equation, so 7(4) +1
= 29.
The required measure of line segment DE is 29.
Given that,
A line segment DF is given,
E is a point on the segment DF, where DE = 7x +1 and EF = 4x - 3
and DF = 42,
To determine the measure of DE.
A line is a straight curve showing the shortest distance between 2 points.
Here,
DF = DE + EF
From the given put the values of DF = 42, DE = 7x +1 and EF = 4x - 3
42 = 7x + 1 + 4x - 3
42 = 11x - 2
11x = 44
x = 4
DE = 7x + 1
Put the value of x in above equation,
DE = 7 * 4 + 1
DE = 28 + 1
DE = 29
Thus, the required measure of the DE segment is 29.

Step-by-step explanation:
Given that:
Mikayla bought a bag of 84 pieces of candy.
she wants to divide them evenly and place them into bag such that they are not more than 20 bags.
Therefore, the number of possible ways she can do that is ;

find the distance between each points (-1,4) (1,-1)
Answer: The distance is about 5.39 units
Step-by-step explanation:
To find the distance between the two points find the difference in the x and y coordinates and square them to add them and find their square root.
4-(-1) = 5
-1 -1 = -2
5^2 + -2^2 = d^2 where d is the distance
25 + 4 = d^2
29 = d^2
d = [tex]\sqrt{29}[/tex]
d= 5.39

what is the measure of X?
angles are not necessarily drawn to scale
Answer:
xº=71º
Step-by-step explanation:
Take the triangle BDH
Once the sum of interior angles of a triangle is 180º:
40º+31º+yº=180º
71º+yº=180º
yº=109º
Once yº and xº are supplementary angles (add up to 180º):
yº+xº=180º
109º+xº=180º
xº=71º
If ∠DBE is 40° and ∠BDC is 31° then the angle x will be equal to 71°.
What is triangle?A triangle is a two dimensional figure having three sides, three angles and the sum of all the angles is equal to 180°.
How to find angle?We have been given ∠DBE=40° and ∠BDC=31° and we have to find the angle ∠IHE which is x°.
Let the angle DHB equal to y.
In ΔBDH
∠DBH+∠BDH+Y=180 { Sum of all angles in a triangle is equal to 180}
40+31+y=180
71+y=180
y=180-71
y=109°
We know that sum of two angles on a line is equal to 180°.
So, x=180-109
x=71°
Hence the value of x is 71° if ∠BDC=31° and ∠DBE =40°.

(7x + 6)
10. Write an equation to determine the value of x.
11. Find the value of x.
Answer:
10). 5x + (7x + 6) = 90
11). x = 7
Step-by-step explanation:
From the picture attached,
Sum of given angles measures 90°
Measures of the angles are (5x)° and (7x + 6)°
Therefore, equation to determine the values of x will be,
5x + (7x + 6) = 90
By combining similar terms of the equation,
12x + 6 = 90
12x = 90 - 6
12x = 84
x = [tex]\frac{84}{12}[/tex]
x = 7
Therefore, by solving the equation value of x will be 7.

Step-by-step explanation:
10 × 3 + 4 + 5 × 2 + 1 + 3 × 100 = 345
Using PEMDAS, multiply first ... then add/subtract.
30 + 4 + 10 + 1 + 300 = 345
34 + 10 + 1 + 300 = 345
44 + 1 + 300 = 345
45 + 300 = 345
345 = 345
