Let William be x years old.

Thomas = (4 + x) years

In five years,

William = (x + 5) years

Thomas = 4 + x + 5 = (9 + x) years

Given, in five years sum of their ages is 24.

x + 5 + 9 + x = 24

2x + 14 = 24

2x = 24 - 14

2x = 10

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

x = 5

Hence, William is 5 years old and Thomas is 9 years old.

Serjik [45]

B: 914-20(27.80)=X, multiply: 20(27.80)=556, 914-556=$358 :A.

C: 914-27.80=$886.20 :)

What is the area of the parallelogram?

Bezzdna [24]

The area of the parallelogram is mathematically given as

A = 7 square units Option B

<h3>What is the area of the parallelogram?</h3>

Generally, the equation for a parallelogram is mathematically given as

A=bH

Where

$b=\sqrt{4^2+1^2}$

b=4.123

and

H=1.75

Hence

A=3*1.75

A=7.2square units

In conclusion, a parallelogram

A = 7 square units
