If you want to add or subtract fractions :
1- make sure that the denominators of the fractions are equal. if they are not, then multiply each of them by a number so that they will be equal.
2- add or subtract the numerators.(if you already had multiplied the denominator of a fraction by a number, then you should multiply the numerator by the same number and do the adding or subtracting)

here are the answers :





good luck
112 ft. You multiply 14*8 to get that, the area
Answer:
-1/3
step-by-step explanation:
-21=-39k+-24
39k = -24 + 21
39k = -3 (divide each side by 39)
k = -1/3
Point slope form is

where

are a point that the line passes through and

is the slope
I guess solve for 1 y and get the constants to the left side3y=x+11divide both sides by 3

there you have it:

it passes through the point (-11,0) and has a slope of 1/3
