Answer:
27
Step-by-step explanation:
72(−3/8) = (x/72)72
-3×9=x
x=-27
Since 4 gallons of paints were used to paint 25 chairs, the paint used for 1 chair is going to be 4/25
I believe the correct answer is B. I really hope this was the correct answer and helped you out.
First calculate the future value
The formula is
A=p (1+r/k)^kt
A future value?
P present value 6599.2
R interest rate. 0.042
K compounded monthly 12
T time 7 years
A=6,599.2×(1+0.042÷12)^(12×7)
A=8,850.16
Now calculate the interest earned
I=A-p
I=8,850.16−6,599.2
I=2,250.96
Hope it helps!
f(x+1) = 16(x+1)² - (x+1) = 16(x²+2x+1) - x - 1
= 16x² + 32x + 16 - x - 1 = 16x²+31x+15
so
f(x+1)-f(x) = 16x²+31x+15 - (16x² - x)
= 16x²+31x+15 - 16x² + x
= 32x + 15
