On a map, the scale is 1 inches = 50 miles. For each map distance, find the actual distance for: 12 inches

600 miles

Step-by-step explanation:

Since the scale is given as 1 inch = 50 miles

Then to get the distance when given 12 inches in a map we do cross multiplication as follows

1 inch = 50 miles

12 inch=x miles

By cross multiplication

1 inch*x miles=50 miles *12 inches

Making x the subject of formula then

X=50*12/1=600 miles

Therefore, the actual distance is 600 miles

i am not sure :

step-by-step explanation:

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!
