Answer:
49x^2+28xy+4y^2
= (7x)^2 + 28xy + (2y)^2
= (7x + 2y)^2
= 7x+4y
=D
Step-by-step explanation:
Answer:
Step-by-step explanation:
3x + 4y = 16
- 3x - 3x

I am joyous to assist you anytime.
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

Hope this helps!
Answer:
y < 623.5
Step-by-step explanation:
Let the number be y
250yrs(1) - y < 3/5(1) + y
250 - y < 3/5 + y
combine the like terms
250 - 3/5 < y +y
250 - 3/5 < 2y
make 250 and 3/5 a single fraction first by finding the LCM of 5 and 1 which is 5. Multiply by their LCM.
(250/1)5 - (3/5)5
1250 - 3 < 2y
1247 < 2y
divide both sides by 2
y < 1247/2
y < 623.5
