Answer:

Step-by-step explanation:

Area of square  = 479

Side² = 479

Take square root both sides

\sqrt{Side^{2}}=\sqrt{479}\\\\Side = 21.88\\\\Side = 22 ft

Answer:

A

Step-by-step explanation:

Formula is y=(x-h) Where h is the number the function is moved left or right...since it is supposed to be moved right, then (x-9) should probably work

<h3>Answer: 5.5 which is choice B</h3>

Have a look at the diagram I posted below. I marked on your image to add in another angle. This angle is also 20 degrees because of congruent alternate interior angles (horizontal lines are parallel). This angle I add in is the reference angle of the triangle

opposite the reference angle is the vertical side x

adjacent to the reference angle is the horizontal side 15

We'll use the tangent rule. Make sure your calculator is in degree mode.

tan(angle) = opposite/adjacent

tan(20) = x/15

15*tan(20) = x <<-- multiply both sides by 15

x = 15*tan(20)

x = 5.45955 <<--- use calculator; this is approximate

x = 5.5 <<--- round to one decimal place

Let f () = + 5 and g(x) = 2x - 3<br> Find f (x) g(x)
Nina [5.8K]

Answer:

2x^{2}+7x-15

Step-by-step explanation:

I presume f(x)=x+5 and g(x) =2x-3 and the question is f(x)*g(x)

f(x)*g(x)

(x+5)(2x-3)

distribute

2x^{2}+10x-3x-15

2x^{2}+7x-15

1) 2x + 8y = 20 what's the solution so confused <br> y = 2
postnew [5]
If y is equal to 2 then you can find x by putting 2 for y so you will have:
2x + 8(2) = 20 
2x + 16 = 20 
2x = 20 - 16
2x = 4 
x = 4/2 
x=2 :)))
i hope this is helpful
have a nice day
