Answer:
48x
Step-by-step explanation:
2(3x)+4(48x)−3(50x)
Multiply 2 and 3 to get 6. Multiply 4 and 48 to get 192.
6x+192x−3×50x
Combine 6x and 192x to get 198x.
198x−3×50x
Multiply 3 and 50 to get 150.
198x−150x
Combine 198x and −150x to get 48x.
48x

Answer:
Answer Below
Step-by-step explanation:
For a triangle the area is calculated using the formula: Area = half of base by altitude. A = 0.5 X b X a.
So to calculate the volume of a triangular prism, the formula is: V = 0.5 X b X a X h.
You can also search "how to find the volume of a triangular prism" and there will be a base calculator so u can figure out this problem!
Since the perimeter of the square is 16cm, each side is 4cm.
If we subtract the area of the two unshaded triangles from the area of the square we will know the area of the shaded portion...
The small inverted triangle on the left has a height of 4 and a base of 1. The are of the bottom triangle has a height of 2 and a base of 4...
So the area of the two triangles is 4*1/2+2*4/2=2+4=6
The area of the square is just 4*4=16 so:
The shaded area is 16-6=10cm^2
The proportion of the shaded area to the total area is then:
10cm^2:16cm^2
5:8
