Find the perimiter of this shape

juin [17]

Answer:

The perimeter of the shape is (7x²+10x+81) inches.

Step-by-step explanation:

When finding the perimeter of a shape, you have to add up all the side lengths :

$p = 31 + (4 {x}^{2} + 8x) + (3 {x}^{2} - 5x + 20) + (7x + 30)$

$p = 31 + 4 {x}^{2} + 8x + 3 {x}^{2} - 5x + 20 + 7x + 30$

$p =( 7 {x}^{2} + 10x + 81) \: inches$

What is the value of x in the equation 6(x + 1) – 5x = 8 + 2(x – 1)?

ycow [4]

Answer:

$x=0$

Step-by-step explanation:

we have

$6(x+1)-5x=8+2(x-1)$

solve for x

$6x+6-5x=8+2x-2$

Group terms that contain the same variable and move the constants to the other side

$6x-5x-2x=8-2-6$

$-x=8-8$

$x=0$
