The statement is false.


If a parallelogram is reduced to have dimensions that are half as long, then the perimeter isalso half the original length.


If you imagine a square with sid lengths of 4, the original perimeter is 16. When the dimensions are halved to be 2, the new perimeter is 8. 8 is half of 16, not a fourth of 16.

Two rectangular prisms have the same volume. The area of the base, B, of the blue prism is 418 square units. The area of the bas
kenny6666 [7]

Answer:

The height of the blue prism is half the height of the red prism

Step-by-step explanation:

Represent the volume of the blue prism with Vb and the red prism with Vr

So, we have:

V_r = V_b

A_b = 418 --- base area of the blue

A_r = \frac{1}{2}A_b --- base area of the red

Required

Determine which statement about the heights of the prisms is true

Volume is calculated as:

Volume = Base\ Area * Height

For the blue prism:

V_b = A_b * h_b

For the red prism

V_r = A_r * h_r

Equate both volumes

V_r = V_b

A_r * h_r = A_b * h_b

Substitute the expression for A_r

\frac{1}{2}A_b * h_r = A_b * h_b

Divide both sides by A_b

\frac{1}{2} h_r =  h_b

<em>This implies that the height of the blue prism is half the height of the red prism</em>

Y=x<br> y=-6x–14<br><br> (substitution method)
olga_2 [115]

Answer:

The solution is the point (-2,-2)

Step-by-step explanation:

we have

y=x ----> equation A

y=-6x-14 ----> equation B

Solve the system by substitution

substitute equation A in equation B

x=-6x-14

Solve for x

6x+x=-14\\7x=-14\\x=-2

Find the value of y

substitute the value of x in the equation A

y=x

so

y=-2

therefore

The solution is the point (-2,-2)
