Answer:

24

Step-by-step explanation:

You need to plug in 3 for all of the x-values

That looks like 2(3)^2 + 5(3) - 9

Then if you simplify it is 2(9) + 15 - 9

Then simplify one last time and you get a final answer of 24

Please help, I need to get this done!<br>I need to get number 16, 17, and 18 done please help!!!!​
Tresset [83]

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.

Hope it helps and is correct!
