Answer:
A = 100 B = 130 C = 150
Step-by-step explanation:
Translated into a system of equations:
A+B+C = 380
B = A+30
C = B + 20
So we find B from the last one:
B = C-20
Plug it in the second one:
C-20 = A+30
A = C-50
Plug it in the first:
C-50 + C-20 + C = 380
3C - 70 = 380
3C = 450
C=150
A = C - 50 = 150 - 50 = 100
B = C - 20 = 150 - 20 = 130
Answer:
12x+4
Step-by-step explanation:
For the perimeter, we have to add up all sides of the triangle.
(3x-4) + (4x+5) + (5x+3)
3x-4+4x+5+5x+3
(3x+4x+5x) + (-4+5+3)
12x+4
The length of the rectangle is 10 inches, and the width is 6 inches.
10 + 10 + 6 + 6 = 32
And that's your answer! ^ I hope this helped! c:
