Answer:

The answer is 9x² + 3x - 2.

Step-by-step explanation:

1) Collect like terms.

$(7x^{2} + {2x}^{2} ) + ( - 2x + 5x) + (8 - 10)$

2) Simplify.

${9x}^{2} + 3x - 2$

Therefor, the answer is 9x² + 3x - 2.

Since they are intersecting lines, you would equal them to each other.
(5x+4)= (8x-71)
-8x. -8x
-3x + 4 = -71
- 4. -4
-3x = -75
Divide 3x by both sides gets you x = 25

Galina-37 [17]

Common ratio = 8/2 = 32/8 = 4

10th term = a1*r^(n - 1) where a1 = 2 , r = 4 and n = 10
= 2 * 4^9

Margarita [4]

Answer:

C. 40in

Step-by-step explanation:

$a^{2}+b^{2} =c^{2} \\$

so...

$24^{2} +32^{2} =c^{2}$

$24^{2} = 576\\32^{2} =1024$

576+1024=1600

$\sqrt{1600} = 40$

the missing side = 40in
