Answer:
22.4
Step-by-step explanation:
using altitude theorem, the height of the triangle is 20
let y = height
10/y = y/40
y² = 400
y = or 20
Now we can us the Pythagorean Theorem to find 'x':
10² + 20² = x²
100 + 400 = x²
x= ≈ 22.4
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
