Answer:
16
Step-by-step explanation:
8*2
4(2x+10)= 0
8x+40=0
subtract 40 from both sides
8x+40-40=0-40
8x=-40
x=-40/8
x=-5
4(2x-10)=0
8x-40=0
Add 40 from both sides
8x-40+40=0+40
8x=40
x=40/8
x=5
Answer:
6
Step-by-step explanation:
5*6=30
7*6=42
Answer:
The quadratic equation that best models the volume of the box (in terms of W) is:
Step-by-step explanation:
The perimeter of the rectangular base = 28cm
Perimeter of a rectangle = 2(L+W)
2(L+W)=28
L+W=14
L=14-W
Volume of the Box= LWH
Since L=14-W and Height Of the Box= 5cm
Volume of the Box= (14-W)W X 5
