Answer:

The area of the circle is 314mm²

Step-by-step explanation:

To solve this problem we have to use the formula for calculating the area of a circle

a = area

π = 3.14

r = radius

d = diameter

r = d/2

r = 20mm / 2

r = 10mm

a = π * r²

we replace the known values

a = 3.14 * (10mm)²

a = 3.14 * 100mm²

a = 314mm²

The area of the circle is 314mm²

4x + 5x + 12 = 6(x-2)<br> Math

Rashid [163]

Hi there! :)

$\large\boxed{x = -8}$

4x + 5x + 12 = 6(x - 2)

Combine like terms and distribute the coefficient outside of the parenthesis:

9x + 12 = 6(x) + 6(-2)

9x + 12 = 6x - 12

Subtract 6x from both sides:

9x - 6x + 12 = 6x - 6x - 12

3x + 12 = -12

Subtract 12 from both sides:

3x + 12 - 12 = -12 - 12

3x = -24

Divide both sides by 3:

3x/3 = -24/3

x = -8.
