Answer:
Step-by-step explanation:
Expand brackets.
Combining like terms.
Step-by-step explanation:
2x-y=14-------(1)
2x+y= -2------(2)
(1) +(2)
2x-y+2x+y=14+(-2)
4x = 12
x = 3
so from------ (1)
2x -(3) = 14
2x = 17
x = 17/2

Answer:
y = -3x - 6
Step-by-step explanation:
Your y-intercept is given as b = -6
Rise/run = 3/-1
There's a negative slope here
y = -3x - 6
We can represent the width as x and the length as x+5. Then we can make the area formula A=(x)*(x+5), plug in 36 for A, and solve for x
36=x^2+5x (distribute)
0=x^2+5x-36
0=(x+9)(x-4)
So x=-9 and 4 but dimensions can't be negative so x=4
So if the width is 4, then the length is 9 (4+5)
Hope this helps :)
