Answer:
4 ft , 16 ft & 20 ft
Step-by-step explanation:
40 = x + 4x + 5x = 10x --> x = 4
P=2L+2W
P=(2*4)+(2*8)
P=8+16
P=24
The solution to the system of equation are x = -2 and y = 3
<h3>How to find the solution of a system of equation?</h3>
x + 3y = 7
2x + 4y = 8
Let's isolate x in the first equation
x = 7 - 3y
substitute the value of x in the second equation.
Therefore,
2(7 - 3y) + 4y = 8
14 - 6y + 4y = 8
-2y = 8 - 14
-2y = -6
y = -6 / -2
y = 3
Hence,
x + 3(3) = 7
x = 7 - 9
x = -2
