Answer:

6 ft

Step-by-step explanation:

The surface area of a cube is given by

SA = 6s^2

216 = 6s^2

Divide each side by 6

216/6 = 6s^2/6

36 = s^2

Take the square root of each side

sqrt(36) = sqrt(s^2)

6 =s

Each side is 6ft

What is the value of y in the system of equations?<br> 5x + y = -1<br> y = 6x + 10
Vinil7 [7]

Answer:

y = 4

Step-by-step explanation:

5x + y = -1

y = -1 - 5x

y = 6x + 10

6x + 10 = -1 - 5x

11x = -11

x = -1

y = 6x + 10 = 6(-1) + 10 = -6 + 10 = 4

Help me please explain do not need work just explain THANK YOU I NEED HELP
Mnenie [13.5K]
Alright, 

you will need to solve for each variable to find if they got the equation correctly or not.. 

Let's start with h 
isolate h 
(1/2)h = A/(b1+b2)
Now we need to get rid of 1/2 we may do so by multiplying both sides by 2 

h = 2(A/(b1+b2))

And that's not how they did it for h so Option D doesn't apply 


Let's see C
Also doesn't apply since they multiplied 2 only by A rather than A/h

Let's see B
Also not correct they made the same mistake as with option C

Let's see A
again same mistake 
when multiplying both sides by 2 
the 2 should be as following 
2\frac{A}{h}

I believe you should contact your instructor and explain that non of the options is right.

Permiter math equation help pls
Anestetic [448]

Hi

First dont panic. this one is pretty easy.

you known that the perimeter is the addition of every sides of a figure.

you have the total perimeter : 84.6

so now you just have to withdraw every side you have to the total , and the missing measure will be the result.

have a try ! you can make it.
