Answer:

Step-by-step explanation:

Part A

9x^2 + 24x + 16

= (3x + 4)(3x + 4)

length of each side = 3x + 4 units.

Par B

16x^2 - 25y^2

= (4x + 5y )( 4x - 5y)

length = 4x + 5y and width = 4x - 5y

A quarter throws a football from a height of 6.5 feet with an initial velocity of 64 feet per second
ohaa [14]

Answer:

0.10s

Step-by-step explanation:

Given data

DIstance= 6.5ft

velocity = 64 feet per second

with the parameters given above, we can find the time taken as

velocity = distance/time

time= distance/velocity

time= 6.5/64

time= 0.10 seconds

Hence the time the ball took is 0.10s

12 A highway had a landslide, where 3,000 cubic yards of material fell on the road, requiring 200 dump truck loads to clear. On another highway, a slide left 40,000 cubic yards on the road. How many dump truck loads would be needed to clear this slide?
3,000 yd3 = 200 dtl
40,000 yd3 × 200 dtl = 2,667 dtl
3, 000 yd3
