\frac{1}{3}x=14+5 \\
\frac{1}{3}x=19 \\
\frac{1}{3} \cdot 3 x=19 \cdot3 \\
x=57

Also need help with this problem too if anyone can help

Answer:

A=24 sq ft

P=20 ft

Step-by-step explanation:

To make this easier, separate the triangle and the rectangle. To find the area of the triangle multiply the bases and the height and then divide the answer by. So,

(6x4)/2

(24)/2

A=12

The base of the triangle is the same as the base on the rectangle. To get the perimeter, add the 3 side values up.

5+5+6

P=16

For the rectangle, to get the area, just multiply the base value and the height value. So,

(6x2)

A=12

To get the perimeter, add all the side values up. So,

6+6+2+2

P=12

Add the 5 sides of the pentagon up for the perimeter.

5+5+2+2+6

P=20

And finally, add the area of the triangle and the rectangle to get the area of the pentagon.

12+12

A=24

daniiel is currently 26 years older than his son. in 6 years he will be three times older than his son. how old are both of them
Molodets [167]

Answer:

Daniiel is 33 years old.

The son is 7 years old.

Step-by-step explanation:

x+26=3x

The x represents the son.

To solve for x:

-26=x-3x

-26=-2x

x=13

Since the father will be 3 times his son's age in six years we subtract 6.

x=7

This means the son is 7 years old as of right now. To find the father's age you do 7+26=33
