1 and 2 are less then 3
4=3+1 but you cant get 1 from 7 or 3 so 4 is impossible. So is 5, 6, 8, and 20.
Bolded numbers are answers.
Answer:
The answer is explained below.
Step-by-step explanation:
To begin, it is necessary to discard 1 and 2 because the minimum score is 3.
Number 5 is another one, since it is not possible to score 3+2 with the given conditions.
Number 8 is another option because it would be necessary to score 3+3+2 (not possible) or 6+2 (not possible.)
Number 11 would require 6+1+3+1 which is not possible.
Answer: C. 6 x 1/4
hope it helps!
-x^2 - 7x + 4
2x(x - 1) - 3x^2 - (5x - 4)
= 2x^2 - 2x - 3x^2 - 5x + 4
Adding like terms, we get:-
-x^2 - 7x + 4 (answer).
perimeter =2 (l+b)
140=2 (l+40)
140=2l+80
120/2=l
l=60
