Answer:
- 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope (gradient) and c the y- intercept )
Given
2y = - 3x - 8 ( divide all terms by 2 )
y = -
x - 4 ← in slope- intercept form
with gradient = - 
The base is 315. Perimeter of base is 72.
X best represents
the width must be x so that the length can be 12+x meaning that the length is greater than length by 12
How I was taught: Make sure both numbers are a fraction. If not put "1" as the denominator. Multiply straight across. Simplify if you can.
It would be D:7
It needs to have one side bigger than
