Answer: x = -5/2 and x = -3/2
Step-by-step explanation:
(2x + 5)2 = 4x (x + 5) +25
4x + 10 = 4x² + 20x + 25
[minus 4x on both sides.]
10 = 4x² + 16x + 25
[minus 10 on both sides.]
0 = 4x² + 16x + 15
ac = 4(15) = 60,then find the factors that add up to 16, which is 6 and 10.
0 = 4x² + 6x + 10x + 15
0 = 2x(2x + 3) + 5(2x + 3)
0 = (2x + 5)(2x + 3)
2x + 5 = 0 2x + 3 = 0
2x = -5 2x = -3
x = -5/2 x = -3/2
Ratio of girls to boys is 3:2....added = 5.....this means that 3/5 of the total students are girls and 2/5 of the total students are boys.
so if there are 50 students...
3/5(50) = 150/5 = 30 girls
2/5(50) = 100/5 = 20 boys
Answer:
2 (941 - 16)
Step-by-step explanation:
You need to first find a number that is a factor of 1882 and -32
In this case it would be 2
So you factor out 2
= 2 (941 - 16)
Answer:
$10,560
Step-by-step explanation:
Given the MSRP as $22,000 and the residual value as 48%, the residual value of the car can be calculated as:
#Hence, the car's residual value at the end of the lease period is $10,560
