A blueprint of a house shows a bedroom with an area of 12 square
inches. If the blueprint's scale is
1 inch : 3 feet, what would be the
actual square footage of the bedroom?
square feet

215.92 dollars is the answer

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

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!
