Takes -7multiplies the term n + 3. we have -7n -21. and -8 multiplies each term of 1+ 8n we have : -8  -64n.

here are numbers :
-7(n+3) - 8(1 + 8n)
-7n -21 -8 -64n= 0 (then take all the number to the other side. = 21 +8 = 29)
-81n = 29
n = 29/ -81

Find the area of the figure given to the right. Round to the nearest whole number. 22 15 36 S The area of the figure is ft2​
Ede4ka [16]

Answer:

Step-by-step explanation:

Area of left rectangle:

Length = 36 ft

Width  = 8

Area1 = length * width

         = 36 * 8

        =  288 square feet

Area of right rectangle:

Length = 15 ft

Width = 22 - 8 = 14 ft

Area2 = 15 * 14

          = 210 square feet

Area of the figure = Area1 + area2

                            = 288 + 210

                            = 498 square feet

What is the area of the given sector
Romashka-Z-Leto [24]
Assuming the shape is a piece of a circle, you can determine the ratio of the shape to a full circle. A full circle will have 360 degree but this shape is only 40 degree. Then the ratio would be: 40/360= 1/9 full circle.

Then, using the circle area formula, the area of the 1/9 circle would be: 
full circle area= pi * r^2
full circle area= 22/7 * 6^2
full circle area= 792/7
1/9 full circle area= 792/7*9= 88/7 = 12.57

The surface area is made up of six sides and the area is then just the sum of the areas of the six sides...

A=2xy+2xz+2yz

A=2(xy+xz+yz)  in this case:

A=2(5*4.5+5*3.5+4.5*3.5)

A=2(22.5+17.5+15.75)

A=2(55.75)

A=111.5 in^2
