Crank3 years ago
4 0

Answer:

5.)

15.36+x=32.11

15.36+x-15.36=32.11-15.36

x=32.11-15.36

x=16.75

6.)

-2(a-3b+c)

-2a+6b-2c

7.)

3a+15y-5a=-a+2(3-a)

-2a+15y= -a+6-2a

-2a+15y=-3a+6

-2a+15y+2a=-3a+6+2a

15y=-a+6

15y/15=-a+6/15

y=-a+6/15

I hope this is good enough:

Need help fast please! Factor by grouping. 6x³ + 24x² -7x -28 =
olchik [2.2K]

Answer:

(x+4)(6x^2 - 7)

Step-by-step explanation:

Focus on the first 2 terms first and on the second 2 terms last:

6x^3 + 24x^2 = 6x^2(x+4)

-7x-28 = -7(x+4)

We see that the factor (x+4) is common to both pairs:  common to the first 2 terms and common to the last 2 terms.

Thus,

6x³ + 24x² -7x -28 = (x+4)(6x^2 - 7(x+4)

Factoring out x+4, we get (6x^2 - 7), and so 6x³ + 24x² -7x -28 in factored form is (x+4)(6x^2 - 7).

A body builder consumed 5,600 calories yesterday. Today, he consumed 4,200 calories.
hammer [34]

well, the difference from 5600 to 4200 is 1400.

If we take 5600 to be the 100%, how much is 1400 off of it in percentage?

\begin{array}{ccll} amount&\%\\ \cline{1-2} 5600&100\\ 1400&x \end{array}\implies \cfrac{5600}{1400}=\cfrac{100}{x}\implies 4=\cfrac{100}{x} \\\\\\ 4x=100\implies x=\cfrac{100}{4}\implies x=25
