Question

can someone please help? If you could Atleast explain question 1 and 4 that would help. but preferably ig someone could awnser and explain all the questions ​

Answer 1

Area = Base • Height

1) 3 • 7

2) 4 • a

3)
`m^(2)`

4) 4(x + 1) = 4x + 4

5) 7(d + 4) = 7d + 28

6) y(y + 3) =
`y^(2)` + 3y

Explanation:

They are asking for an expression. An expression is made up of terms, variables, and an operation. They do not contain equal signs.

For questions 4 through 6, they want you to use the distributive property. There is no way of solving them without having either the length of both sides or the total area.

Answer 2

1)7*3

4)m^2

Explanation:

The first four problems deal with the area of the rectangle, or length times width(7*3,m*m=m^2).

The last four problems are dealing with adding areas. Find the area of the two rectangles(length times width), then add them together to find the total area.
