<span> L is the length and W is the width of the rectangle. L = W + 3 

The Perimeter = 2L + 2W = 2(W + 3) + 2W = 4W + 6 

The Area = L W = (W + 3) W = W2 + 3 W 

The Area and Perimeter are equal in value, so 

W2 + 3 W = 4W + 6 

Now the above quadratic equation for W and we substitute to find L btw 

W = 3 and L + 6

I hope this helped!</span>

So,
Perimeter = 2L + 2W = 2(W + 3) + 2W = 4W + 6 

Area = L W = (W + 3) W = W2 + 3 W 

= W2 + 3 W = 4W + 6 

= W = 3 and L + 6

Hope this helps!

Determine the unknown angle measures in the figure.<br><br>HELP NOW!!! please
maw [93]

Answer:

m∠1=80°

m∠2=112°

m∠3=131°

m∠4=80°

m∠5=37°

Step-by-step explanation:

First you have to find m∠2

To do that find m∠6 (I created this angle shown in pic below)

Find m∠6 by using the sum of all ∠'s in a Δ theorem

m∠6=180°-(63°+49°)

m∠6=68°

Now you can find m∠2 with the supplementary ∠'s theorem

m∠2=180°-68°

m∠2=112°

Then you find m∠5 using the sum of all ∠'s in a Δ theorem

m∠5=180°-(112°+31°)

m∠5=37°

Now you can find m∠1

m∠1=180°-(63°+37°)

m∠1=180°-100°=80°

m∠4 can easily be found too now:

m∠4=180°-(63°+37°)

m∠4=80°

m∠3=180°-49°

m∠3=131°

A survey all beings on plant Kent found that 20 beings preferred Freon juice to all other juices. If 50 beings surveyed altogeth
Ugo [173]

Answer: 40%

Step-by-step explanation:

Since 20 beings preferred Freon juice to all other juices and there were 50 people that were surveyed, the percentage of those that preferred Freon Juice will be:

= Those that preferred Freon Juice / Total number surveyed. × 10

= 20/50 × 100

= 40%

What is the y-intercept of the line perpendicular to the line y = negative three fourthsx + 5 that includes the point (−3, −3)?
NNADVOKAT [17]

Answer:

b = 1

Step-by-step explanation:

y = -\frac{3}{4}x + 5

The line perpendicular to this is:

y = \frac{4}{3}x + b    (We don't know the y-intercept, but we can solve for it since we have a given ordered pair, (-3, -3))

-3 = \frac{4}{3}*(-3) + b    (Simplify)

-3 = -4 + b    (Add 4 to both sides)

b = 1
