Heya!
Here is your answer:
2 ×

+10
we know that,

= 9
so,
2×9 +10
According to BODMAS (bar, Order, division, multiplication, addition, subtraction)
we multiply 2×9 = 18
then,
18+ 10
= 28
Answer:
2feets per year
Step-by-step explanation:
49,5-38,5=11feets --->this is how much it grew in 5,5years
11/5,5=2feets/year --->this is the yearly rate
F(x)=x^2+2x+1 & g(x)=3(x+1)^2
now, f(x)+g(x)
=x^2+2x+1+3(x+1)^2
=x^2+2x+1+3(x^2+2x+1)
=x^2+2x+1+3x^2+6x+3
=4x^2+8x+4<===answer(c)
next:
f(x)=x^2-1 & g(x)=x+3
now, f(g(x))=(x+3)^ -1
=x^2+6x+9-1
=x^2+6x+8<====answer(b)
i solve two of ur problems.
now try the 3rd one that is similar to no. 1
