grigory [225]

Answer: The product of $(9t-4)(-9-4)$ is -117t+52.

Explanation:

The given expression is,

$(9t-4)(-9-4)$

Simplify the above expression.

$(9t-4)(-13)$

Use distributive property t simplify the above expression.

$(9t-4)(-13)=9t\times (-13)-4\times(-13)$

$(9t-4)(-13)=117t+52$

Therefore, the product of $(9t-4)(-9-4)$ is -117t+52.

What does W prime V prime and U prime equal

choli [55]

Answer:

W' = (0, 1.5)

V' = (1, 2)

U' = (1.5, 0)

Step-by-step explanation:

Multiply each coordinate of the given points by the scale factor 0.5

0*0.5 = 0

3*0.5 = 1.5

2*0.5 = 1

4*0.5 = 2

So thats why W(0,3) becomes W'(0, 1.5), and why V(2,4) becomes V'(1,2), and why U(3,0) becomes U'(1.5, 0)

If the volume of a rectangular pyramid is 150 inches cubes ,what is the volume of a prism with the same demensions

Ugo [173]

$\bf \stackrel{\textit{volume of a pyramid}}{V=\cfrac{Bh}{3}}\qquad \qquad \stackrel{\textit{volume of a rectangular prism}}{V=Bh}\qquad \begin{cases} B=base~area\\ h=height \end{cases}$

so let's notice, the volume of the rectangular prism is really 3 times as much of that of a pyramid with the same Base and Height.

so if the pyramid has a volume of 150, the prism will have volume of 3*150.
