5x+3=2(x+9) can someone me on this plz

5x+3=2(x+9)

5x + 3 = 2x + 18 > expand by using distributive property

3x + 3 = 18 > subtract 2x from both sides then simplify

3x = 15 >  subtract 3 from both sides then simplify

x = 5 > divide both sides by 3 then simplify

Answer

x = 5

5x+3=2(x+9)                 Apply distributive law  to the parentheses:-

5x +3 = 2x + 18

5x - 2x = 18 - 3

3x = 15

x = 5 answer

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
