First one
20=n/5+10
minus 10 both sides
10=n/5
times 5 both sides
50=n
2.
hmm
expand
p(x)=2x^2+5x+3-3x-3n
p(x)=2x^2+2x+3-3n
it looks like the coefients of the x terms are divisble by 2
because
if we have
p(x)=2(something)
the p(x) is divisible by 2
therefor that factor is 2 or -2
find what value of n works
so
3-3n=a multipule of 2
we are given
-3,-2,0,2
try each
3-3(-3)=3+9=12, that's divisble by 2
3-3(-2)=3+6=9, that's not divisible by 2
3-3(0)=3, that's not divisble by 2
3-3(2)=3-6=3, that's not divisble by 2
the onnly one that woks is when n=-3
answer is A
Answer:
400 cents or four dollars
Step-by-step explanation:
If 2x10=20, then you could multiply the 40 by 10 to get the answer.
Answer:

Step-by-step explanation:
SI=PTR/100
=9*1*750/100
=$ 67.50
In 6 yrs= 67.50*6
=$405
2y^2+7yvn+3v^2n^2 is the product. hope it helps..
