A cross section of a rectangular pyramid is made perpendicular to the base and through the vertex as shown. Describe the shape and dimensions of the cross section. Use the drop-down menus to explain your answer. A triangular prism with a rectangular base. The base measures 5 centimeters by 12 centimeters. The height of the prism is 8 centimeters. A vertical triangular cross section is drawn through the prism from the top vertex to the base of the prism parallel to the 5 centimeter side of the base.

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!
