1 = 1 x 10 exponent 0
27.5 = 2.75 x 10 exponent 1
Answer: 
Step-by-step explanation:
The area of a rectangle can be calculated with this formula:

Where "l" is the length and "w" is the width.
You can identify from the figure that the length and the width of this rectangle are:

Then, you need to substitute this lenght and this width into
:

Now, apply Distributive property:

Finally, you need to add the like terms. Then, you get:

Answer:
y-24=m(x--4)
Step-by-step explanation:
point slope form:
y-y₁=m(x-x₁)
1) find the slope or "m" first:
slope formula: (y2-y1)/(x2-x1)
(-53-24)/7+4
-77/11=-7
slope=-7
so
y-y₁=-7(x-x₁)
y1=24
x1=-4
y-24=m(x--4)
hope this helps!
