The perimeter of the figure is 35 feet. Find x, then find the length of each side.
maksim [4K]

The value of x is 7 and the lengths of the sides are 16, 11 and 8

<h3>How to determine the values of x and each side?</h3>

The complete question is added as an attachment

The perimeter is calculated as:

P = 3x - 5 + 2x-3 + 15 - x

Evaluate

P = 4x + 7

The perimeter is 35.

So, we have

4x + 7 = 35

This gives

4x = 28

Divide by 4

x = 7

Substitute x = 7 in 3x - 5, 2x-3 and 15 - x

3x - 5 = 3* 7 - 5 =16

2x-3 = 2* 7 - 3 =  11

15 - x= 15 - 7 = 8

Hence, the value of x is 7 and the lengths of the sides are 16, 11 and 8

4. ABCD below is a rectangle. BE=6x+2 and ED=4x+6. Find the length of AC.
Nikolay [14]

Answer:

28 units

Step-by-step explanation:

ABCD is a rectangle. AC and BD are diagonals intersecting at point E.

Diagonals of a rectangle bisect each other.

\therefore BE = ED

\therefore 6x + 2 = 4x + 6

\therefore 6x - 4x= 6-2

\therefore 2x= 4

\therefore x= \frac{4}{2}

\therefore x= 2

\therefore 6x + 2= 6*2+2= 12+2= 14

\therefore BE= 14\: units

\because BD = 2BE

\therefore BD = 2(14)= 28\: units

\because AC = BD (diagonals of a are equal in measure)

\therefore AC = 28\: units
