Answer:
7161 km³
Step-by-step explanation:
28²+b²=32.5²
784+b²=1056.25
b²=1056.25-784
b²=272.25
b=√272.25
b=16.5
1/2x28x16.5x31=7161
Answer: Start with the second expression. That factors easily into (8x-3)(8x+3).
Since 64x^2 + 48x + 9 has no negative signs, I'd bet that the common factor is (8x+3). Divide 64x^2 + 48x + 9 by that to verify.
hope this helps <3
The two factors are 2 and p=10 so I used your equations and
Amortization Solution:
A= P[[r(1+r)^n]/[((1+r)^n)-1)]]
P= $175,000
r= .06/12; divide interest rate by 12 to get monthly interest of 0.005
n=15*12=180; multiply by 12 to get the total number of payments
A= $87500 is the total cost of principal with interest rate of 0.5% monthly
Ok so,
20*2= 40
20*1/2=10
40+10=50
So Johncan travel 50 km in 2 1/2 hours.
Hope this helps :)
