8 - 4 = 7 - 3 because it has a equal sign in the middle meaning that you have to find an equation that’s equal to it. So thats why the missing number is 3

are you serious? If you are, here’s the explanation:
It’s like finding x
8-4=7-x
Let’s simplify it, we know that 8-4=4
4=7-x
Now, we wanna get x by itself, since that’s what we’re looking for.
Go ahead & get rid of 7. Since 7 is a positive number, well subtract it. Also, remember that what we do on one side, we must do to the other side, so subtract 7 on BOTH sides
4-7=-x
Simplify.
-3=-x
Now, we need x to be positive, so let’s get rid of the negative sign (-).
We’ll do this by dividing -1 on BOTH sides.
3=x ——> x=3
Hope this helps! :)

Sketch the algebra-tile shape at right on your paper. Write an expression for the

Dima020 [189]

Answer:

Part 1) $P=(4x+4)\ units$

Part 2)

a) $P=32\ units$

b) $P=26\ units$

c) $P=13\frac{1}{3}\ units$

Step-by-step explanation:

<u><em>The complete question in the attached figure</em></u>

Part 1) Write an expression for the perimeter of the shape

we know that

The figure is composed by a larger square, a rectangle and a smaller square

1) The area of the larger square is given

$A=x^2\ units^2$

so

The length and the width of the larger square is x units

2) The area of the rectangle is given

$A=x\ units^2$

so

The length of the rectangle is x units and the width is 1 unit

3) The length and the width of the smaller square is x units

see the attached figure N 2 to better understand the problem

Find out the perimeter

The perimeter is the sum of all the sides.

so

$P=(x+x+x+x+1+1+1+1)$

$P=(4x+4)\ units$

Part 2) Find the perimeter for each of the given values of x.

a) For x=7 units

Substitute the value of x in the expression of the perimeter

$P=(4(7)+4)=32\ units$

b) For x=5.5 units

Substitute the value of x in the expression of the perimeter

$P=(4(5.5)+4)=26\ units$

b) For x=7/3 units

Substitute the value of x in the expression of the perimeter

$P=(4(\frac{7}{3})+4)=\frac{40}{3}=13\frac{1}{3}\ units$
