A square brick is 11 inches on each side. What is the area of one face of the break?

Answers

All sides of a square are the same so if the length of one is is 11 inches, then all of the sides are 11 inches.
To work out the area of a square you multiply the length and the width.
In this case the sum would be: 11 x 11
The answer to that is 121.
So overall, the answer would be 121 inches.

Answers

Let's simplify step-by-step.7x−6y+3x+3y−3=7x+−6y+3x+3y+−3Combine Like Terms:=7x+−6y+3x+3y+−3=(7x+3x)+(−6y+3y)+(−3)=10x+−3y+−3Answer:=10x−3y−3

Since all the functions in here are addition and subtraction, you can remove the parentheses and just combine like terms.
$(7x-6y)+(3x+3y-3) \n 7x-6y+3x+3y-3 \n 7x+3x+3y-6y-3 \n (7x+3x)+(3y-6y)-3 \n 10x+(-3y)-3 \n 10x-3y-3$

The answer is 10x-3y-3.

What is the area, in square centimeters, of the shape below?

Answers

Answer:

21.46 cm squared

Step-by-step explanation:

3.8x5.8=21.46

Final answer:

The area of a shape can be calculated by multiplying its dimensions. Given a rectangle with length 0.6238 cm and width 6.6 cm, you would multiply these figures to get an area of 4.1 cm².

Explanation:

To calculate the area of a shape in square centimeters, you need to know the dimensions of the shape. For example, if you have a rectangle, you would multiply its length by its width to get the area. If the length was 0.6238 cm and the width was 6.6 cm, the area would be 0.6238 cm x 6.6 cm = 4.11708 cm². However, we often round to two significant figures, so the area would be 4.1 cm². Remember that area is expressed in square units, so for centimeters, the area would be in square centimeters.
