Answer:
7x+9
Step-by-step explanation:
f(x)=7x-5
g(x)=x+2
f[g(x)]= Substitute g(x) in for x in the function f(x)
=7(g(x))-5
= 7( x+2) - 5
Distribute
= 7x+14 - 5
Combine like terms
=7x +9
Answer:
6 or -6
Step-by-step explanation:
The symbol √ is the square root symbol.
The square root of a number is a number that when you multiply it by itself you get the first number.
For example:
The square root of 9 is 3 since 3 times itself, 3 × 3, is 9.
The square root of 9 is also -3 since (-3) × (-3) is 9.
The question is asking for the positive and negative square roots of 36.
What number multiplied by itself is 36?
The answer is 6 since 6 × 6 = 36 and -6 × -6 = 36
