Arectangle has a width of 5 inches and a length of 9 inches. what will be the new dimensions of the rectangle after it is dilated by a scale factor of 3? a) 8 inches by 12 inches b) 15 inches by 9 inches c) 15 inches by 27 inches d)45 inches by 81 inches

To solve this problem you must apply the proccedure shown below:

 1. When a rectangle is dilated by a scale of factor, you must multiply the original dimensions by this scale of factor to obtain the new dimensions.

 2. The original dimensions are: The width is  and the length is 

 3. Therefore, the new dimensions are:

 The answer is the option C: C)  by 

5.25 ounces

step-by-step explanation:

divided 3/4 and 6

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!
