you do 5x13 which equals 65 then 9+15 which equals 24 so 24=65
we can rule out the others because they logically just dont make sense-
1. 29-5 is 24 not negative -24, if you calculated 5-29 it's -29
2. I really don't know ;(
3. no solution
D, B, and A
He needs 4 1/3 buckets of fish.
140 - 75 = 65 pounds of fish left to eat
15x = 65
x = 65 / 15
x = 4 1/3 buckets of fish left to eat
the height it 15 and ur gat
x= -3 and
to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into
where a is the cube root of .
here this is 27 and the cube root of 27 is 3. so we write using the form:
set each factor to 0 and solve for x.
the quadratic expression does not factor and must be solved using the quadratic formula.
where a = 1, b=3, and c=9
this cubic has two complex roots.
