8 0

Answer:

Its either 300 or 315

Step-by-step explanation:

Mainly because 20 ×15= 300 but the triangles on the side, I can't figure it out. I eliminated 82 and 420, 420 mainly because I got it wrong and 82 doesn't make sense.

Answer:

a=3, c=-4, x=8

Step-by-step explanation:

5=4a-7

4a-7=5

4a=5+7

1. What is the perimeter of the figure below. Simplify.<br> 4x^3-5x 2x^3+6x 6x^3+x

____ [38]

Answer:

$12x^3+2x$

Step-by-step explanation:

The perimeter of a polygon is equal to the sum of its sides.

The sides in the triangle shown have lengths $2x^3+6x$ , $4x^3-5x$ , and $6x^3+x$ in no specific order.

Since its perimeter is given by the sum of its sides, the perimeter is equal to:

$2x^3+6x+4x^3-5x+6x^3+x$

Combine like terms:

$\boxed{12x^3+2x}$
