The verbal description are matched with the mathematical expressions as follows:

The cube of the sum of 7x and 8 ⇒ (7x + 8)³

8 added to 7 and x cubed ⇒ 7x³ + 8

8 added to the cube of 7x ⇒ (7x)³ + 8

7 times the cube of the sum of x and 8 ⇒ 7(x + 8)³

Answers and justitication:

1) (7x)^3 + 8→ 8 added to the cube of 7x

becasue the cube of 7x is (7x)^3 and then 8 is added to it.

2) (7x + 8)^3 → the cube of the sum of 7x + 8

because first you add 8 to 7x and then the result is cubed.

3) 7x^3 + 8 → 8 added to 7 and x cubed.

4) 7(x+8)^3 → 7 times the cube of the sum of x and 8.

because first 8 is added to 8, then the result is cubed, and finally the result is multiplied by 7.

What is the area of the shape below

Bad White [126]

Answer:

The area of the shape is $A=886 \:cm^2$ .

Step-by-step explanation:

The shape in the graph is a composite figure is made up of several simple geometric figures such as triangles, and rectangles.

Area is the space inside of a two-dimensional shape. We can also think of area as the amount of space a shape covers.

To calculate the area of a composite shape you must divide the shape into rectangles, triangles or other shapes you can find the area of and then add the areas back together.

First separate the composite shape into three simpler shapes, in this case two rectangles and a triangle. Then find the area of each figure.

To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.

The area of the first rectangle is $A=34\cdot 16=544\:cm^2$

The area of the second rectangle is $A=11\cdot19=209\: cm^2$

The area of a triangle is given by the formula $A=\frac{1}{2} bh$ where <em>b</em> is the base and <em>h</em> is the height of the triangle.

The area of the triangle is $A=\frac{1}{2} \cdot 14\cdot19=133\:cm^2$

Finally, add the areas of the simpler figures together to find the total area of the composite figure.

$A_{composite\:shape}=544+209+133=886 \:cm^2$

I really need help with this please ! I don't understand it, and I have a quiz tomorrow

erik [133]

You can do this by finding a number close to it, and then finding out how to do it.

For example with 63(square root sign), find out what is close to it.

7x7=49 while 8x8=64

Because of this, we now know that it is between 7 and 8 but is also really close to 8.

Our number could be 7.9

Hope this helped!!!
