Answer:

Step-by-step explanation:

First, you must distribute 5 to (x + 3)

5(x + 3) - 5x

5x + 15 - 5x

5x - 5x +15

(You can typically say 0x + 15, as a representation to show there are no more x values, but it is bet not to show any if there are none left)

(5x - 5x will cancel out, leaving only 15)

= 15

1. 7 + 5x = 3 - 2x and 7 + 7x = 3<br> Are they equivalent, if so what is X

oksano4ka [1.4K]

Answer: They are equivalent, and x = -4/7

Step-by-step explanation:

Fist we need to see what the answers to each of these equations are

7 + 5x = 3 - 2x

Subtract 7 on each side

5x = -4 - 2x

Add 2x

7x = -4

X = -4/7

Now the second one

7 + 7x = 3

Subtract 7

7x = -4

X = - 4/7

They are equal and x = -4/7

The perimeter of a square in which A=169cm square root 2?

sergey [27]

I'm guessing you mean:
$A = 169 \sqrt{2}$

If not, correct me.

So, then the perimeter of a square is just 4*A, which in this case would be:
$4(169 \sqrt{2}) = 676 \sqrt{2}$

And that would be your answer: $676 \sqrt{2}$ units²

Place the indicated product in the proper location on the grid. <br> -2x^2y^3 · 14x^2y^3

mojhsa [17]

We have the following product:
-2x ^ 2y ^ 3 · 14x ^ 2y ^ 3
For power properties we have:
"same base add the exponents"
We have then:
(-2 * 14) (x ^ (2 + 2)) (y ^ (3 + 3))
-28x ^ 4y ^ 6
Answer:
The product -2x ^ 2y ^ 3 · 14x ^ 2y ^ 3 is:
-28x ^ 4y ^ 6
