You solve this problem by factoring. After I have factored it, the problem looks like this:
(2x - 5)(x + 1)
Then the first answer would be solved this way:
2x = 5
x = (5/2)
The second answer would be:
x = -1
Hope this helped!
Answer:
Step-by-step explanation:
Side c = AB can be found using the Pythagorean theorem:
c² = a² + b² = 8² +5² = 89
c = √89 ≈ 9.43
__
Angle B is the complement of angle A, so is ...
B = 90° -A = 90° -58° = 32°
c is approximately 9.43; the measure of angle B is 32°.
There are 1000 millimeters in a meter and 0.001 meters in a millimeter

Answer:
$880
Step-by-step explanation:
If r is the rent charged, then the number of $40 increments of increase will be ...
(r -800)/40
and the number of occupied apartments will be ...
120 -5(r -800)/40
The gross income (g) will be the number of apartments times the rent charged, or ...
g = r×(120 -5(r -800)/40) = (1/8)r(1760 -r)
The equation describes a parabola with zeros at r=0 and r=1760. The vertex will be on the line of symmetry, halfway between those zeros. The maximum gross income will be had when the rent is 1760/2 = 880.
$880 should be charged for rent to maximize gross income.
