A rectangular room is twice as long as it is wide, and its perimeter is 48 meters. Find the width of the room.

Dimas [21]

Answer:

The width of the rectangular room =x= 8

Step-by-step explanation:

Given: A rectangular room is twice as long as it is wide, and its perimeter is 48 meters.

To find: The width of the room.

Solution: Let the width of the rectangular room= x meters, then the length of the rectangular room will be = 2x.

Now, Perimeter of rectangular room=2(l+b)

⇒48=2(2x+x)

⇒24=3x

⇒x=8 meters

Then, the width of the rectangular room =x= 8 meters and the breadth of the rectangular room=2x=2(8)=16 meters.

What is the sum of the polynomials 5 a squared b plus 2a squared b squared 5 a2b+2a2b2 and negative ab squared plus a squared b

cupoosta [38]

The first polynomial is $5a^2b+2a^2b^2$

The other polynomial is $-ab^2+a^2b^2$

Now to add polynomials we must add or subtract like terms

Adding them we have

$(5a^2b+2a^2b^2)+(-ab^2+a^2b^2)$

$5a^2b+2a^2b^2-ab^2+a^2b^2$

Here $2a^2b^2 $ and $ a^2b^2 $ are like terms $$

So we add then

We get

$5a^2b+3a^2b^2-ab^2$

The addition of the polynomial is $5a^2b+3a^2b^2-ab^2$

Use Law of Sines or Law of Cosines to solve for the missing parts of each triangle

ella [17]

Answer:

$x = 9.7$

Step-by-step explanation:

Given

The attached triangle

Required

Find x

Using law of sine, we have:

$\frac{a}{sin A} = \frac{b}{Sin B}$

So, we have:

$\frac{x}{sin 32} = \frac{18}{Sin 100}$

Make x the subject

$x = \frac{18 * sin 32}{Sin 100}$

$x = \frac{18 * 0.5299}{0.9848}$

$x = 9.685$

$x = 9.7$ -- approximated
