Answer:
x = -9
Step-by-step explanation:
2x + 5 = -13
- 5 = -5
<u>2x</u> = <u>-18</u>
2 2
x = -9
Because domain restrictions apply to this rational expression, x cannot be equal to {-2, 2}.
<h3>What is domain?</h3>
Domain restrictions are any points in the domain where the function will not have a value. This basically means that there is a point in the function where x will not work.
For the numerator, any value of x will suffice. We can have a value of 0 in the numerator, or a positive, negative, or decimal number.
However, the denominator cannot be equal to zero. This is due to the fact that a fraction bar represents division, and we cannot divide by zero.
Here,
x²-4=0
Add 4 to both sides:
x²-4+4 = 0+4
x² = 4
Take the square root of both sides:
√x² = √4
x = 2 or x = -2
The x cannot be equal to {-2, 2} as domain restrictions apply to this rational expression.

Subtract 'x' from each side. Then 3 > 5 . No value for 'x' can make that statement true. The inequality has no solution.
The area of the smaller figure would be found by multiplying its base length by its height. The height is explicitly provided while the base length is not.
To find the base length of the smaller figure, subtract the shorter length on the bottom (3.1 inches) from the total length on top (6.1 inches).
6.1 - 3.1 = 3
3 * 3 = 9
Answer:
The area of the figure at the right is 9 square inches.
