So first, just simply solve both and then it become obvious. The expression 3-(2+5), you can evaluate what's inside the parentheses first and then your answer will be in the form of a integer: 3-(2+5) = 3-7 = -4 With the second one, your answer will be in the form of a simplified expression because we don't know what x is: 3x-(2x+5) = 3x-2x-5 = x - 5 Also, in the second one, you have to expand the parentheses in order to simplify it.

Find the area of the shaded region

VikaD [51]

Answer:

Area of the shades region = 244.6 ft²

Step-by-step explanation:

Area of the shaded region = Area of the rectangle ABCD- Area of the right angle triangle DEC

Area of the rectangle = Length × width

= 29.8 × 13

= 387.4 ft²

By applying Pythagoras theorem in the right triangle DEC,

(Hypotenuse)² = (leg 1)² + (leg 2)²

CD² = DE² + EC²

(29.8)² = DE² + (28)²

888.04 = DE² + 784

DE² = 888.04 - 784

DE = 10.2 ft

Area of ΔDEC = $\frac{1}{2}(\text{Base})(\text{Height})$

= $\frac{1}{2}(10.2)(28)$

= 142.8 ft²

Area of the shades region = 387.4 - 142.8

= 244.6 ft²

This creates a cone! :) the formula for volume of it is 1/3 pi R^2 (h) just in case!
