Answer:
One solution
Step-by-step explanation:
3(x – 2) = 22 – x
Distribute
3x - 6 = 22 -x
Add x to each side
3x-6+x = 22-x+x
4x -6 =22
Add 6 to each side
4x-6+6 = 22+6
4x = 28
Divide by 4
4x/4 = 28/4
x = 7
Your first step is to do 6(x) which is 6 multiplied by x which is the value of 5\6
Answer:
530.998cm^2
Step-by-step explanation:
General formula for the area of a circle is πr^2
And π is given to be 3.142
R is 13 cm
So let's apply the formula
Area=3.142×(13^2)
Area=3.142×169
Area=530.998cm^2
So the area of the circle is 530.998cm^2
Answer:
a. blue 16x + 5
a. red 4x + 5
b. 12x
c. blue 53
c. red 17
Step-by-step explanation:
a.
The perimeter of a polygon is the sum of the lengths of the sides of the polygon.
Blue triangle:
side lengths: 4x + 2, 5x - 4, 7x + 7
perimeter = 4x + 2 + 5x - 4 + 7x + 7 = 16x + 5
Red triangle:
side lengths: x + 3, x + 7, 2x - 5
perimeter = x + 3 + x + 7 + 2x - 5 = 4x + 5
b.
We subtract the perimeter of the red triangle from the perimeter of the blue triangle.
16x + 5 - (4x + 5) =
= 16x + 5 - 4x - 5
= 12x
c.
Blue triangle:
perimeter = 16x + 5 = 16(3) + 5 = 48 + 5 = 53
Red triangle:
perimeter = 4x + 5 = 4(3) + 5 = 12 + 5 = 17
