sergey [27]

Answer:

a) 12

b) 13

Step-by-step explanation:

f(x) = x^2 + 3

g(x) = 2x - 1

a) f(g(2)) = ?

g(2) = 2(2) - 1

= 4 - 1

= 3

f(g(2)) = f(3) = 3^2 + 3

= 9 + 3

= 12

b) g(f(2)) = ?

f(2) = 2^2 + 3

= 4 + 3

= 7

g(f(2)) = g(7) = 2(7) - 1

= 14 - 1

= 13

Which expression is equivalent to 3 p+15? (4 points)
Deffense [45]

Answer:

um, I am confused on the answer options, but 3(p+5) is equivalent

Step-by-step explanation:

3p+15 is the same a 3(p+5) because in 3(p+5) we have to use the distribution property

So, it is 3p +15 here's a picture to explain it better

(3(p+45) would be too big of a number as you also use the distribution property and it would be 3p+135)
