Answer:
See answers below.
Step-by-step explanation:
<u>Large Rectangle:</u><u> </u> length x width = (x + 3)(x - 4) =
x² - 4x + 3x - 12
x² - x - 12
<u>Smaller Rectangle:</u> length x width = (x)(3) = 3x
<u>Shaded Region: </u>shaded area = lg. rectangle minus small rectangle
A = (x² - x - 12) - 3x
A = x² - 4x - 12
<u>Solve for x, if shaded reion's area is 48 square units: </u>
48 = x² - 4x - 12
x² - 4x - 12 -48 = 0
x² - 4x - 60 = 0
(x - 10)(x + 6) = 0
x - 10 = 0 or x + 6 = 0
x = 10 or x = -6
But x represents a length, so x cannot be -6.
x = 10
Answer:
x > 7
Step-by-step explanation:
Given
4x + 6 < 6x - 8 ( subtract 6x from both sides )
- 2x + 6 < - 8 ( subtract 6 from both sides )
- 2x < - 14
Divide both sides by - 2, reversing the symbol as a result of dividing by a negative quantity.
x > 7
Answer:
alternate..so i think it was 60°
The decimal point should be moved 4 places to the right
