Answer:
9x^2-25
Step-by-step explanation:
You can solve this problem by using FOIL:
- FOIL (First, Outer, Inner, Last)
First: 3x*3x= 9x^2
Outer: 3x*-5= -15x
Inner: 3x*5 = 15x
Last: 5*-5= -25
Now add what we got together:
9x^2 -15x +15x -25
Answer: 9x^2 - 25
Note: Whenever when we see conjugates(coefficients of variables are same but real numbers are opposites) like these we can ignore the outer and inner of the foil process as they cancel out.
Hope this helps!
Answer:
172.7sqft (square feet)
Step-by-step explanation:
SA = 2(pi)(r)(h) + 2(pi)r^2
plug in the radius, height, and find SA, then multiply by 10 fenceposts.
SA= 2(3.14)(.5)(6)
Solve
SA=14.39166
Multiply by 12
Answer is 172.7sqft
Hope this helps!
So first we start with division:
$750 divided by 2 equals $375.
Since one employee gets more than the other, we need to add more onto his/her salary.
So, next is addition.
$375 plus $200 equals $575.
So, one employee makes $375 while the other has an increase in his salary, so they get paid $575.
Hope I helped you!
Answer:
x=10 5x=50 2x=20
Step-by-step explanation:
5x+2x+110=180
180-110=70
7x=70
x=10
5*10=50
2*10=20
