<u>Step-by-step explanation:</u>

3y⁸ + 12y⁶ - 15y⁴

= 3y⁴(y⁴ + 4y² - 5)

= 3y⁴(y² + 5)(y² - 1)

= 3y⁴(y² + 5)(y - 1)(y + 1)

Answer:y= (3/4)x -7/4

Step-by-step explanation:

[y -(-1)]/[x - 1] = [2 -(-1)]/[5 - 1]

[y + 1]/[x - 1] = 3/4

y + 1 = (3/4)x - 3/4

y = (3/4)x - 7/4.

the area of a trapezoid is 36 square inches. The height is 4 inches and one bases twice the length of the other base. What are t

vlada-n [284]

The formula for this is $A= \frac{1}{2} ( b_{1} + b_{2} )h$ . Filling in accordingly, $36= \frac{1}{2}(x+2x)(4)$ . This simplifies to $36= \frac{1}{2}(3x)(4)$ and 36=6x. Therefore, x = 6 so the bases are 6 and 12.
