Luckily was learning the same thing so
We have to replace n with ten
3n^2+7n
3*10^2+7*10=
3*100+70=
300+70=370
But I’m not sure about this answer so plz confirm
Solution:
Let
X = height of Cody on the first day of school last year
Given:
Y= height of Cody on the first day of school year = 165 cm
10%(X)+X=Y
.10(X)+X=165
1.10X=165
X=165/1.1
<span>X=
150 cm = height of Cody on the first day of school last year</span>

Answer:
A
Step-by-step explanation:
f(x)+g(x)=-3x^2+4x+4+x(-7x-7)= -3x^2+4x+4 -7^2-7x
= -10x^2-3x+4
Its 7a so the coefficient of a is 7
