Answer:

TSA = 62 ft^2

The total surface area is 62 ft^2

D. 62

Complete question;

A student draws the net below to show the dimensions of a container that is shaped like a right rectangular prism. What is the total surface area?

A. 19 B. 30 C. 38 D. 62

Attached is the image.

Step-by-step explanation:

Total surface area = Length × breadth

Total surface area is equal to the sum of surface area of section 1(main), surface area of section 2(wing) and surface area of section 3(wing).

TSA = SA1 + SA2 + SA3

TSA = 5×(2+3+2+3) + 3×2 + 3×2

TSA = 50 + 6 + 6

TSA = 62 ft^2

The total surface area is 62 ft^2

Solve the equation. –x 8 3x = x – 6 x = –18 x = –14 x = 2 x = 4
LenKa [72]

The value of the variable x in the equation –x + 8 + 3x = x – 6 is - 14.

<h3>How to find variable in an equation?</h3>

The variables of an equation can be found as follows:

–x + 8 + 3x = x – 6

The variable in the equation is x.

Therefore,

–x + 8 + 3x = x – 6

combine like terms on the left side

-x + 3x + 8 = x - 6

2x + 8 = x - 6

subtract x form both sides of the equation

2x - x + 8 = - 6

x + 8 = -6

subtract 8 from both sides

x = -6 - 8

x = - 14

Sati [7]
If it goes from a higher number to a lower number it is a decrease.

(15,295 - 9182) / 15295....x 100
6113 / 15295 = 0.399....x 100 = 39.9% decrease
