Which expression is equivalent to 3(5p-2)?

Let's simplify this problem using the distributive property.

The first thing we want to do is the change the minus to plus a negative.

So we have 3 (5p + -2).

Now we can distributive or multiply this 3 times each of the terms inside the set of parentheses.

So we get 3 (5p) + 3 (-2) and this simplifies to 15p + - 6.

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.

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
