Answer:
16
Step-by-step explanation:
The quotient of a number (x) and 4 is written x/4. 56 less than that is ...
(x/4) -56
The problem statement tells us the value of this is -52, so we have ...
(x/4) -56 = -52
Add 56 to both sides of this equation, and you get ...
x/4 = 4
Multiply both sides of this equation by 4 and you get ...
x = 16
The value of the unknown number is 16.
Area: 5x² + 7x - 26, Answer C.
To solve the area if the shaded region, let's find the are of the whole figure then find the area of the open rectangle in the center and find the difference of them both.
(3x - 4)(2x + 2)
6x² - 8x + 6x - 8
<span>6x² - 2x - 8
</span>Next, let's solve the area of the open rectangle in the center of the shaded region.
<span>
(</span>x - 6)(x - 3)
x² - 6x - 3x + 18
x² - 9x + 18
Now, let's take the difference between both the areas.
(6x² - 2x - 8) - (x² - 9x + 18)
6x² - 2x - 8 - x² + 9x - 18
5x² + 7x - 26
