1/7 divided by 5/2
8th stuff be like this can someone

dividing by a fraction is the same as multiplying by its reciprocal. in other words, we can change the division sign to multiplication and flip the second fraction.

÷ can be rewritten as

×

now, we are simply multiplying fractions. to multiply fractions, we multiply across the numerators and multiply across the denominators.

1 × 2 = 2

7 × 5 = 35

we do not have to reduce because it's already in lowest terms. therefore, the answer is .

true

explanation:

x= -3 and

step-by-step explanation:

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.

x-3=0

x=3

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.
