Answer:
x = -16
Step-by-step explanation:

Answer:
x=3, y=76
Step-by-step explanation:
You set them equal because you plug in "y" as 22x+10 into "y=20x+16"
22x+10=20x+16
2x=6
x=3
20(3)+16=76
A triangular prisms' formula is: lwh = Length * Width * Height
substitute the variables
L = 21in
W = 15in
H = 17in
21*15*17
= 5,355in
The volume of the figure is: 5,355in^3
Answer:
It very well could be
Step-by-step explanation:
It could be any type of wood, it doesn't matter weight, volume, or size
If 2 triangles are similar, the ratio of one side of the triangle to the corresponding side of the other is always same for all 3 sides.
We can make use of this rule to calculate the length of sides.
From the image,
3 / 15 = 6 / x
Simplify,
1 / 5 = 6 / x
Use cross method to solve this.
5 x 6 = 1 x x
X = 30
Therefore the length of x is 30ft., A.
