Answer:
The length of the rectangle is given as:
(9x + 6)
Step-by-step explanation:
The area of a rectangle is given as:
Length × Width
Area of the rectangle = 45x² − 42x − 48
Width = 5x - 8
We solve for the length of the rectangle by factorising the area of the rectangle
45x² − 42x − 48
45x² - 72x + 30x - 48
(45x² - 72x )+ (30x - 48)
9x(5x - 8) + 6(5x - 8)
(5x - 8)(9x + 6)
Therefore:
The length of the rectangle is given as:
(9x + 6)

Answer: The commercial costs $900 to produce and $110 each time it is aired.
Step-by-step explanation:
Answer:
x = 30
Step-by-step explanation:
These angles are all supplementary (they all add up to 180) so:
x + 3x + 2x = 180
6x = 180
x = 30
Answer:
y > -3/4x +3
Step-by-step explanation:
Add 4y+12, then divide by 4.
-3x +12 < 4y
-3/4x + 3 < y
The solution is ...
y > -3/4x +3
