Answer:
a^2
−10a+21
Step-by-step explanation:
(a−7)(a−3)
Apply the distributive property by multiplying each term of a−7 by each term of a−3.
a^2
−3a−7a+21
Combine −3a and −7a to get −10a.
a^2
−10a+21
Plz be more specific thanks
Answer:
7
Step-by-step explanation:
The formula would be c=(320/x)+3
C is the total chairs and x is the price per chair and we add 3 since she is getting 3 for free
Following PEMDAS, we should do 320/80 first which is 4
Then the equation becomes 4+3=7
