Explain why the expression 7•3x is not equal to the expression 21x
1 answer:
Working out the expression 7(3ˣ) is first to calculate the value of 3ˣ then multiply the answer to 7.
For example, let x = 2
Then 7(3ˣ) = 7(3²) = 7 × 9 = 63
With the same value of x = 2, calculating 21ˣ = 21² = 441, which isn't the same answer with the expression 7(3ˣ)

Answer:
Part a: 3
Part b: B
Step-by-step explanation:
3*3=9*3=27
27/3=9
F(x)= 4(1-3)+1
4(-2)+1
-8+1
-7
G(x)=(1-3)^2-5
-2^2-5
4-5
-1
A. -14x+21
because -7 times 2x is -14x and -7 times -3 is 21
