First we need to get x
<RNA = <ENV [v.o.a]
8x+12=5x+57
8x-5x=57-12
3x=45
x=15
<ENV= (5×15+57)
<ENV =132
the answer is D
Answer:
3.864
Step-by-step explanation:
convert 8% to decimal, you get .08
multiply that by 4.2 and you get 0.336, which means that 0.336 is 8% of 4.2
subtract 0.336 from 4.2
3.864
Answer:
The required Principal Amount = 7,250.

or, P = 7,250
Hence, the required Principal Amount = 7,250.
answer
f(-5)=115
Step-by-step explanation:
x+5=0
x=-5
f(x)=3x^2-7x+5
f(-5)=3*(-5)^2-7(-5)+5
f(-5)=3*25+35+5
f(-5)=115
