Answer:
7,11
Step-by-step explanation:
The width is x. x+4= the length. The area is side times side, so it’s
x × (x+4) = 77
We can simplify this to:
x × x + x × 4 = 77
x^2 + 4x = 77
x^2 + 4x - 77 = 0 This is a quadratic equation. So we can solve using the quadratic formula:
x = 
->
That’s the positive solution and that’s x, the width. So the width is 7 and the length is 7+4=11
Answer: 44
Step-by-step explanation:
Answer:
ok so the answer o Y is -8 bc 4-12 = -8 so really is -8
Step-by-step explanation:
In order to figure this out you need to use slope intercept for for each of these hills. Let's say the first hill is HA and the second hill is B
slope intercept: y = mx + b
HA: y = (2/10)x
HB: y = (2/15)x
As you can see when you plot this on a graph, HB is steeper because the line rises more sharply.
