Answer:
Step-by-step explanation:
The formula of a surface area of a rectagular prism:
l - length
w - width
h - height
We have the dimensions 6cm × 14cm × 5cm. Substitute:
12h-9h=3h move everything else to other side
3h=20-40+6
3h=-14
divide by 3
h=-14/3
By elimination:
y = 3x - 1
y = 2x + 2
Subtract the second equation from the first
0 = x - 1
y = 2x + 2
Subtract the first equation from the second
0 = x - 1
y = x + 3
Subtract the first equation from the second again
0 = x - 1
y = 4
Subtract x from both sides of the first equation
- x = - 1
y = 4
Divide the first equation by (-1)
x = 1
y = 4
<h3>
So, the solution is x = 1 and y = 4 {or: (1, 4)}</h3>
