(x+2)(x+3)=x•x-10 how do you solve for x?

x = -16/5

Step-by-step explanation:

Let's solve your equation step-by-step.

(x+2)(x+3)=xx−10

Step 1: Simplify both sides of the equation.

x^2 + 5x + 6= x^2−10

Step 2: Subtract x^2 from both sides.

x^2 +5x +6 − x^2 = x^2 − 10 −x^2

5x + 6 = −10

Step 3: Subtract 6 from both sides.

5x + 6 − 6 = −10 −6

5x = −16

Step 4: Divide both sides by 5.

5x/5 = -16/5

Therefore

x= -16/5

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

may i see the picture? it would a lot, xox
