Simplify brackets

x + -7 = 2

Simplify x + -7 to x - 7

x - 7 = 2

Add 7 to both sides

x = 2 + 7

Simplify 2 + 7 to 9

<u>x = 9</u>

Hello there!


x + (-7) = 2

The rules says: When we have + multiply by -, the answer is -

                          When we have a positive sign multiply by a negative sign, the answer is negative.

Thus,

x - 7 = 2

Add 7 on both sides

x - 7 + 7 = 2 + 7

x = 9

Find the area of the figure to the nearest hundredth.<br><br>​
marysya [2.9K]

Answer:

51.26 ft

Step-by-step explanation:

First find the area of the triangle:

a=1/2 base times height

a=(1/2)(6)(4)

a=12 ft

Now find the area of the circles:

a= pi times radius squared

a= pi times 2.5 squared

a=19.63 ft

19.63 + 12 = 31.63 ft

A trapezoid has an area of 60 square inches. The height of the trapezoid is 5 inches. What is the length of the longer base if t
Vinil7 [7]

Answer:

Step-by-step explanation:

Remark

Let the shorter base = x

Let the longer base = 3x

h = 5

Area = 60

Formula

Area = (b1 + b2)*h /2

Solution

60 = (x + 3x)*5 / 2                Multiply both sides by 2

2*60 = (x + 3x)*5                  Combine like terms

120 = 4x *5

120 = 20x                             Divide by 20

120/20 = x

x = 6

Therefore the two bases are

x = 6

3x = 18
