Answer:
x=5 x = -3
Step-by-step explanation:
-7 / ( x^2 -2x -15)
Factor the denominator
-7
----
(x-5) ( x+3)
The excluded values are when the denominator is equal to zero
(x-5) (x+3) =0
x-5 =0 x+3=0
x=5 x = -3
To figure out which is not equivalent to the others,, we must solve each option provided. x < -2 is already solved,, so there is no need to do any work that option.
The first step for solving x - 2 < 4 is to move the constant to the right side and then change its sign.
x < 4 + 2
Now add the numbers together to get your final answer.
x < 6
This means that we have one option that equals x < -2 and one option that equals x < 6.
Let's now solve 2x < -4 to see what that one equals. In order to solve this,, we need to divide both sides of the inequality by 2.
x < -2
Now we can see that it looks like all of the expressions are equivalent except for x - 2 < 4. Before we can confirm this though,, let's solve for x - 2 < -4. The first step for solving this is to move the constant to the right side and change its sign.
x < -4 + 2
Now calculate the sum of these two numbers to get your final answer.
x < -2
This tells us that all of the options are equivalent except for x - 2 < 4,, or option B.

Answer:
Step-by-step explanation:
Base of the triangle= 37•5m
Height of the triangle= 6•4m
Area of the triangle= 1/2 × base × height
= 1/2 × 37•5 × 6•4
= 120 m^2

The amount of paper that are needed to line the bottom of 3 drawers with paper is equal to 2,160 square inches.
<h3>How to determine the amount of paper?</h3>
First of all, we would calculate the area of the bottom of each drawer as follows:
Area = length × width
Area = 36 × 20
Area = 720 square inches.
Next, we would multiply this area by 3:
Total area = 720 × 3
Total area = 2,160 square inches.
