Answer:

7(x + 7)

Step-by-step explanation:

We see that 7 is a common factor of both the term 7x and the term 49. Then, we can take 7 out from each:

7 * (x + (49/7)) = 7 * (x + 7)

And, that's factored!

So, the answer is 7(x + 7).

Hope this helps!

Use the product property of roots to choose the expression equivalent to 3√5x*3√25x^2?

nignag [31]

Answer: $\sqrt[3]{125x^3}$ .

Step-by-step explanation: Given radical expression

$\sqrt[3]{5x} \times \sqrt[3]{25x^2}$ .

According to the product property of roots.

$\sqrt[n]{a} \times \sqrt[n]{b} = \sqrt[n]{a \times b}$

On applying above rule, we get

$\sqrt[3]{5x} \times \sqrt[3]{25x^2} = \sqrt[3]{5x \times 25x^2}$

5 × 25 = 125 and

$x \times x^2 = x^3$

Therefore,

$\sqrt[3]{5x \times 25x^2}= \sqrt[3]{125x^3}$

<h3>So, the correct option would be second option $\sqrt[3]{125x^3}$ .</h3>

PLEASE HELP ME. IM DESPERATE. MY BRAIN STOPPED WORKING

alexandr1967 [171]

Answer:

All of them except for the 3rd one

Step-by-step explanation:

2) 15 - 3x = 5(x + 4) - 8x

15 - 3x = 5x + 20 - 8x

15 - 3x ≠ -3x + 20

4) 2(x - 7) = 2x - 10

2x - 14 ≠ 2x - 10

1) 24x - 22 = -4(1 - 6x)

24x - 22 ≠ -4 + 24x

3) 12 - 2x = 6(2x + 2)

12 - 2x = 12x + 12

0 = 14x

0 = x, only one that has a solution
