(2.75*15.5)-(2.50*15.5)=
42.625- 38.75=
3.875 or
$3.88
Answer:
C. x^2+2x-10
Step-by-step explanation:
Volume of a Rectangular Prism = LWH
We have the height so we can simplify by dividing it out of the total volume
Then you get x^2+2x-10.
Since the area of the base is LW, that is your answer
Answer:
1) (2, 3)
2) (2, -5).
Step-by-step explanation:
2x – y = 1
2x +2y = 10 Subtract to eliminate the 2x:
2x - 2x - y - 2y = 1 - 10
-3y = -9
y = 3.
Plug this into the first equation:
2x - 3 = 1
2x = 4
x = 2.
2)
5x – y =15
x + y = -3 Adding to eliminate y:
5x + x - y + y = 15 + -3
6x = 12
x = 2
Plug this into the first equation:
5(2) - y = 15
-y = 15 - 10 = 5
y = -5.
