A carpenter wants to expand a square room. The new room will have one side 4 feet longer and the adjacent side 6 feet longer tha

gogolik [260]

Answer:

Dimensions of original room = 12 x 12 feet.

Explanation:

Let the size of old square room be a x a.

New dimension = ( a+4 ) x ( a + 6 )

We have area of the new room will be 144 square feet greater than the area of the original room.

So, ( a+4 ) x ( a + 6 ) = a x a + 144

a²+10a+24= a²+144

10a = 120

a = 12 feet.

Dimensions of original room = 12 x 12 feet.

mezya [45]

There are 150 students in Hannah's school.

Sum of books donated by the students =b.

Average books donated by each student = $\frac{b}{150}$

It is given Hannah donated 3 times as many books each student donated.

Number of books donated by Hannah= $3 times \frac{b}{150} = \frac{b}{50}$

The expression of the number of books donated by Hannah= $\frac{b}{50}$
