A figure containing AB¯¯¯¯¯¯¯¯ is dilated by a scale factor of 3 to form A′B′¯¯¯¯¯¯¯¯¯¯. If AB¯¯¯¯¯¯¯¯ measures 15 units, what is the length of A′B′¯¯¯¯¯¯¯¯¯¯?

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are

none.

step-by-step explanation:

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
