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
Answer:
x=14 to make the pay equal.
Step-by-step explanation:
Okay so what I did here is kind of time-consuming and I'm sure there's a better way, but I used a calculator to substitute a lot of different numbers into the equation to make it equal, and when I got to 14, the equations both ended up as 625.
<span>A) 2x - 4y = 10
B) 7x - 9y = 12
Multiplying equation A by -3.5
A) -7x +14y = -35 then adding B
B) </span><span><span>7x - 9y = 12</span>
5y = -23
y = -4.6
</span>
2x -4*-4.6 = 10
2x + 18.4 = 10
2x = -8.4
x = -4.2
It has one solution (-4.2, -4.6)
