Answer:
Area = 525 ft²
Step-by-step explanation:
Area of rectangle = Length × Width
Length = 20 + 15 = 35 ft
Width = 15 ft
Area = 35 ft × 15 ft = 525 ft²

To do this, we simply add up corresponding row and column elements.

So, we have:

Add

Answer:
x > 6
Step-by-step explanation:
-2x < -12
divide by -2
switch signs because you're dividing by a negative number
-2x/-2 < -12/-2
x > 6
Hope this helps :)
Here is a substitution problem. By saying c is 4, we can replace anywhere we see c with the number 4.
c = 4
4c - 7.8
= 4(4) - 7.8
= 16 - 7.8
= 8.2
Hope this helps! :)
Firstly, we need to understand the formula of point-slope form:

Where x and y is the coordinates and m is the slope respectively.
To find the slope:

In this case:

We can then put the above slope and the point (-1,4) into the formula:
4-y = -1/2(-1-x)
-y = 1/2+1/2x-4
y = -1/2x+7/2
Alternatively:
y-4=-1/2(x-(-1))
y=-1/2x-1/2+4
y = -1/2x+7/2
Therefore the answer is y = -1/2x+7/2.
Hope it helps!
