Answer:
8x² + 96x + 288 = 8(x + 6)²
Step-by-step explanation:
96÷8=12
288÷8=36
8x² + 96x + 288 = 8(x² + 12x + 36)
= 8(x² + 2(1)(6)x + 6²)
= 8(x + 6)²
Answer:
Each algebra book costs $60.
Step-by-step explanation:
A=bill for algebra books; S=bill for science books=A+$360
S+A=$3960 Substitute for S
A+$360+A=$3960 Subtract $360 from each side.
2A=$3600 Divide each side by 2.
A=$1800 The order for 30 algebra books cost $1800.
Individual book=A/30
individual book=$1800/30=$60 ANSWER: Each algebra book cost $60.

Answer:
Acceleration,
Step-by-step explanation:
Given that,
Initial speed = 4 m/s at 2 seconds
Final speed = 32 m/s at 9 seconds
We need to find car's average acceleration. We know that average acceleration is equal to the change in speed divided by the change in time. So,
So, the car's average acceleration is equal to .
