B. To be careful, use brackets: 10(1*2) + 4x which will be 20 + 40x or as you have it, 10*2 + 40x.
Answer:
q=(40-7)/3 or simplified q=11
Step-by-step explanation:
So we know that the perimeter is 40 inches and one of the sides is 7 so logically we do 40-7 to get the length of the three remaining sides combined. Then to find the length q, we have to divide that answer by 3 because the three sides have the same length or (40-7)/3, which simplified is 11, so the length of the side is 11 inches and the expression is q=(40-7)/3.
Answer:
⅓
Step-by-step explanation:
8+7+6
total= 21
blue= 7÷21
1/3
These 'l l' lines mean absolute value. essentially it's asking how many units away from 0 a number is. Because of this all absolute values are positive numbers
l-18l=18
Step-by-step explanation:
the first one is the correct one
a, = -51+12(n-1)
a(2) = -51+12(2-1)=-39
