Answer:

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

Distribute -5 through the parenthesis

-15x - 30 = -3(4x - 2)

distribute -3 through the other parenthesis

-15x - 30 = -3( -12x + 6 )

move the variable the left hand side, change sign

-15x + 12 - 30 = 6

move constant to the right hand side

-15x + 12 = 6 + 30

collect like terms

-3x = 6 + 30

add the numbers

-3x = 36

divide both sides by -3

-3/-3 = 36/-3

x = -12

Answer:

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

-15x-30=-12x+6

-30-6=-12x+15x

3x=-36

x=-36/3=-12

HOW DO I SOLVE THIS PLEASE HELP
malfutka [58]

Answer:

  x = 15

Step-by-step explanation:

We assume you want to find the value of x.

Know (or prove) that in this geometry, all of the right triangles are similar. That means the ratios of corresponding sides are proportional.

  short side / hypotenuse = 9/x = x/25

  x^2 = (9)(25) . . . . . . . . . . multiply by 25x ("cross multiply")

  x = √((9)(25)) = (3)(5) . . . take the square root

  x = 15

Help plz:)))I’ll mark u Brainliest
rodikova [14]

Answe

Step-by-step explanation:

The interior angles of a triangle add up to 180. We know from the photo that there is a 90° angle and an 18° angle, and 90-18 is 72, so the other interior angle is 72°. The question is asking you to find the value of side x, so you'll need to use sin.

sin (72°) = x/16

x ≈ 15.2
