Answer:

(4w^2+180w+1800) meters^2

Explanation:

(60+2w) x (30+2w)

1800+120w+4w^2+60w

Combine like terms and rearrange into quadratic equation

4w^2+180w+1800

Don't forget to put your units and since we are talking about area be sure to add your squared symbol

117 Mr. Turtle, Mrs. Squirrel and Ms. Pigeon work at the Magic Forest's post office. Mr. Turtle can

Using proportions, it is found that the same job will take Mrs. Squirrel 6 hours.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The times are given as follows:

Mrs. Squirrel: x.

Mr. Turtle: 3 days.

Mr. Pigeon: 30 minutes = Half an hour = 1/48 day.

The ratios are as follows:

Turtle/Squirrel = Squirrel/Pigeon.

Hence:

$\frac{3}{x} = \frac{x}{\frac{1}{48}}$

$x^2 = \frac{3}{48}$

$x^2 = \frac{1}{16}$

$x = \sqrt{\frac{1}{16}}$

x = 1/4.

It takes 1/4 of a day for Mrs. Squirrel to do the job, hence 1/4 x 24 hours = 6 hours.

Help? Show work!<br> Triangle PQR ≅ Triangle XYZ<br> PQ = 3a + 4 and XY = 5a – 12. Find a and PQ.

Ivenika [448]

Given:

$\Delta PQR\cong \Delta XYZ$

$PQ=3a+4$

$XY=5a-12$

To find:

The value of a and PQ.

Solution:

We have,

$\Delta PQR\cong \Delta XYZ$

$PQ\cong XY$ (CPCTC)

So,

$PQ=XY$

$3a+4=5a-12$

Isolating variable terms, we get

$3a-5a=-4-12$

$-2a=-16$

Divide both sides by -2.

$a=\dfrac{-16}{-2}$

$a=8$

Now,

$PQ=3a+4$

$PQ=3(8)+4$

$PQ=24+4$

$PQ=28$

Therefore, the value of a is 8 and the value of PQ is 28.

A pair of parallel lines is cut by a transversal, as shown (see figure):

Anestetic [448]

The answer
let p' be the corresponding angle of the angle p (that is because of the prallelism and the transversal, look the image)
but p' and p are correspondant angles implies p'=p,
looking at the figure, p' and q are opposite angles
so q=p' and p'=p implies q=p
the answer is
<span>p = q</span>
