Answer:
56
Step-by-step explanation:
a= 2s +3t
b= -m+4
c= a+2b+c
d= 2x-1
e= x squared + 3x +6
f= 4t-2st-s
When a=-2, and b=5, a+b = -2+5, which is equal to 3.
Let me know if this helps!
A .The expression 2l+2(3l+1) shows the width is 1 more than 3 times the length.
p = 8l + 2
Length = l
Width:
2w = p - 2l
2w = (8l + 2) - 2l
2w = 6l + 2
w = 3l + 1
Therefor w is 3 times the length plus 1
