A rectangular garden has a length of (2y - 4) feet and a width of 4y^2 feet. How do you find the perimeter of the garden

Ber [7]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{8 {y}^{2} + 4y - 8}}}}}$

Step-by-step explanation:

Given,

Length of a rectangular garden ( l ) = 2y - 4

Width of a rectangular garden ( w ) = 4y²

Perimeter of the garden = ?

Finding the perimeter of a rectangular garden having length of 2y-4 and width of 4y²

$\bold{ \boxed{ \sf{perimeter \: of \: a \: rectangle = 2(l + w)}}}$

$\longrightarrow{ \sf2(2y - 4 + 4 {y}^{2}})$

Distribute 2 through the parentheses

$\longrightarrow{ \sf{4y - 8 + 8 {y}^{2} }}$

Arrange it in standard form

$\longrightarrow{ \sf{8 {y}^{2} + 4y - 8}}$

Hope I helped!

Best regards! :D

Rationalize the numerator of (√(3)-9)/4. When I get -78/4√(3)+36. Is that correct?

Zina [86]

That's what I got. to rationalize the numerator you have to multiply by the conjugate, in this case (√3 + 9) / (√3 + 9), which is what it looks like you did.
hope this helps! if you liked this answer please rate it as brainliest!! thank you!!!

a store sells for 25% off the regular price the regular price of a beach towel is 24.50 which expression represents the scale pr

UNO [17]

$24.5 \times 1.25 = 30.625$
Since you're adding on to the regular price, you can say it is 125% of the price. Or you can use the regular equation:
$(24.5 \times .25) + 24.5 = 30.625$
Since you're only finding 25% of 24.5, you have to add on 24.5 because you're paying for the beach towel and applying the sales tax.

Now, since cents are to the hundredths place, you have to round.
The final price would be $30.63
