Answer:

12e - 6f + 20g

Step-by-step explanation:

2(6e - 3f + 10g) is the given equation. Because of the grouping, we know that the entire part in parentheses is multiplied by two. Now the distributive property helps us by letting us multiply each individual part of the parentheses by two.

6e becomes 12e

-3f becomes -6f

and 10g becomes 20g

Now when we put those together, it becomes 12e - 6f + 20g

Hope this helped!

Answer:

16) 62.8 m²

17) 19.4 m²

18) 103.5 m²

Step-by-step explanation:

The formula to find area of a circle is: $\pi r^{2}$ . To find radius, find the half of the diameter.

To solve number 16, first find the area of the unshaded circle using the formula: $\pi 4^{2}$ . This is also 3.14*16. Multiply to get 50.24 m². Now find the area of the larger circle using the formula: $\pi 6^{2}$ . This is also 3.14*36. Multiply to get 113.04 m². Now subtract 113.04 - 50.24 to get the shaded area or 62.8 m².

To solve number 17, first find the area of the square using the formula: side x side. In this case multiply: 5.25 x 5.25 to get 27.5625. Round to the nearest tenth to get 27.6 m². Now find the area of the circle using the formula: $\pi 2.625^{2}$ . This is also 3.14*2.625. Multiply to get 8.2425. Round to the nearest tenth to get 8.2. Subtract 27.6 - 8.2 to get 19.4 m².

To solve number 18, find the area of one unshaded circle using the formula: $\pi 1.75^{2}$ . This is also 3.14*3.0625. Multiply to get 9.61625. Round to the nearest tenth to get 9.6 m². Add 9.6 + 9.6 to find the area of both unshaded circles. You get 19.2 m². Now find the area of the shaded circle using the formula: $\pi 6.25^{2}$ . This is also 3.14*39.0625. Multiply to get 122.65625. Round to the nearest tenth: 122.7. Subtract 122.7 - 19.2 to get 103.5 m².
