<em><u>Complete Question:</u></em>

The rectangle below has an area of x^2-6x-7 square meters and a width of x-7 meters. What expression represents the length of the rectangle?

<em><u>Answer:</u></em>

<h3>The expression represents the length of the rectangle is (x + 1) meter</h3>

<em><u>Solution:</u></em>

Given that,

\text{Area of rectangle} = x^2 - 6x - 7 \\\\Width = x - 7

<em><u>TO FIND: LENGTH = ?</u></em>

We know that,

Area\ of\ rectangle = length \times width \\\\Therefore\\\\x^2 - 6x - 7 = length \times x - 7\\\\length = \frac{x^2 - 6x - 7 }{x - 7 }\\\\length = \frac{(x-7)(x + 1)}{x - 7}\\\\\text{cancel out x-7 from numerator and denominator} \\\\length = x + 1

Thus expression represents the length of the rectangle is (x + 1) meter

Find the result when 90 is decreased by 35%.<br> 58.5<br> 75.6<br> 60.5<br> 78.5
avanturin [10]
In this question, it's asking you to find the number when 90 is subtracted by 35%. So, you find 35% of 90 which is 31.5 and you minus it from 90 = 58.5.

> 90 x 35% = 31.5
> 90 - 31.5 = 58.5

Use the graph of f(x) to find the solution to the equation f(x)=0
myrzilka [38]
The solution will be where the graph crosses the x-axis.

When a graph crosses the x-axis, the value of the function is 0. Just look at your graph and look at the x-values where the graph crosses the x-axis.

Answer:

B. x < -1

Step-by-step explanation:

Hello!

Let's put them in order from greatest to least:

  • \{-2,-5,-9,-12\}

Given our possible inequalities, we need to find the inequality that contains all of these values.

The inequality that works is x < -1, as <u>all values are less than -1.</u>

Therefore, the answer is B. x < -1.
