Question

The picture is above I’ll mark as brainliest.

Answer 1

Answer: ?=5

Step-by-step explanation:

In a rectangle the opposite sides are congruent (same length).

So we have ?+?+3+3=16

Let's use a variable for ?

x+x+3+3=16

Since there are 2 of the variable x we can write it as 2x since 2 of something means it's doubled. We can also combine 3 and 3.

2x+6=16

Let's subtract 6 from both sides.

$2x+6-6=16-6\\2x=10$

Now let's divide both sides by 2 to find the value of x (which is ?)

$\frac{2x}{2} =\frac{10}{2} \\x=5$

The value of x/? is 5.

Answer 2

Answer:

?=5

Step-by-step explanation:

So let's do 16-6 (3*2)

10/2=5
