|-4| would be made into 4 because of absolute value so then we have 14-3
which then is 11 hope this helped!!!!
Answer:
Step-by-step explanation:
Let the rate of commission is x%.
<u>Total earning is:</u>
- 7500 + 120000*x/100 = 13500
- 1200x = 13500 - 7500
- 1200x = 6000
- x = 6000/1200
- x = 5
Answer:
D. 14
Step-by-step explanation:
a^2+b^2=square of c
a^2+x^2=50
Answer:
(15,18)
Step-by-step explanation:
write two equations with the information provided.
2x + 3y = 84
x + 4y = 87
use the property of substitution to answer.
x + 4y = 87, x = 87 - 4y
2(87 - 4y) + 3y = 84
174 - 8y + 3y = 84
174 - 84 = 8y - 3y
90 = 5y
90/5 = y
y = 18
Add the value of Y to an original equation. Solve for X
2x + 3(18) = 84
2x + 54 = 84
2x = 84 - 54
2x = 30
x = 30/2
x = 15
First and last terms of the given equation are perfect squares. They can be written as
(4p^2)^2+ 2.(4p^2).5+(5)^2
It's like identity 1: (a+b)^2=a^2+2ab+b^2
So a=4p^2 and b=5
Therefore it is equal to (4p^2+5)^2
