Answer:

X = 14

Step-by-step explanation:

3(2x+6) = 2(4x-5)

you will need to multiply the outside number to the numbers in the parentheses so now it's: ( I reordered the terms to give you a heads up)

6x + 18 = 8x - 10

Reordered:

18 + 6x = -10 + 8x

Now let's solve for X

18 + 6x = -10 + 8x

Now combine like terms

18 + -2x = -10

Now subtract 18 to get -2x alone

18 + -2x = -10

-18            -18

Now it's:

-2x = -28

Now divide by -2 to get x alone

-2x = -28

/-2    /-2

And now it's:

X = 14

<u>Answer:</u>

A. (x+5)

<u>Step-by-step explanation:</u>

We are given a quadratic expression x^2+8x+15 which we will factorize to see which of the given options is a binomial factor of it.

x^2+8x+15

Finding the factors of 15 such that when added, they give a result of 8.

x^2+3x+5x+15\\\\x(x+3)+5(x+3)\\\\(x+3)(x+5)

Therefore, we can see that (x+5) is that binomial factor that is present in the given options so option A. (x+5) is the correct answer.

Answer:

first answer

Step-by-step explanation:

Hi, this is correct because repeating decimals are rational numbers.

Rational numbers can be written by a fraction of integers.

If there is a pattern, it means that this is the division of two integers.

The perimeter of a triangle is 29. One side of a triangle is 5 less than twice the side of the shortest length. The third side i
PolarNik [594]

Answer:

  • 7, 9, 13

Step-by-step explanation:

Let the sides of the triangle be a, b and c.

<u>We have:</u>

  • P = a + b + c = 29
  • a = 2b - 5
  • c = b + 6

<u>Substitute values and solve for b:</u>

  • 2b - 5 + b + b + 6 = 29
  • 4b + 1 = 29
  • 4b = 28
  • b = 7

<u>Find a and c:</u>

  • a = 2*7 - 5 = 14 - 5 = 9
  • c = 7 + 6 = 13

<u>The sides are:</u> 7, 9, 13
