Answer:
see below
Step-by-step explanation:
We can write the length as w + 8 and since area is length * width our answer is w * (w + 8) = w² + 8w.
Answer:
x = 14
Step-by-step explanation:
2x+4 - 12 = 20
2x - 8 = 20
2x = 28
x = 14
Answer:
120
Step-by-step explanation:
10% = 12
50% = 60
100% = 120
Answer:
m=3/4
Step-by-step explanation:
First, let us remind ourselves of the slope formula: m=rise/run=(-)/(-)
Let's pick two points from the graph to work with. Let's do (3,-6) and (-1,-9).
And let 3=, -6=, -1=, -9=.
1. Substitute the values into the slope formula: [-9-(-6)]/(-1-3)
2. simplify the expression: [-9-(-6)]/(-1-3)=(-9+6)/-4=-3/-4=3/4
3. As a result, the slope of the line is 3/4
