Pyramid x is similar to pyramid y. The surface area of pyramid x is 135 cm² and the surface area of pyramid y is 240 cm². if the volume of pyramid x is 189 cm³. then what is the volume of pyramid y?
A. 448 cm³
B. 336 cm³
C. 1061.9 cm³
D. 252 cm³

B. 336 cm^3

Step-by-step explanation:

Set up a proportion: 135/x=240/y

135/189=240/y

135y=189(240)

135y=45360

y=336

Therefore, B. 336 cm^3

I hope this helped and have a good rest of your day!

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
