Surface area = area of the square + 4 * area of 1 of the triangles
= 4*4 + 4 * 1/2 * 4 * 8
= 16 + 64 = 80 in^2 Answer

How do you do that?????

Elden [556K]

This question is easy once you understand. So when adding, subtracting, multiplying, or dividing with whole numbers you turn it into a fraction. So 12 is going to become 12/1. 8 1/8 is a mixed number so we have to turn it into an incomplete fraction. Here is how you do it. Multiply the denominator by the who number. So 8 x 8 = 64. Then you add your product to the numerator, which will make it 65. Then after this you keep your denominator giving you 65/8. Now we have to find the common denominator by finding the LCM. So the LCM is 8. Next we divide the old denominator by the new denominator. So 1 goes into 8, 8 times. And next 8 x the numerator. so 8 x 12 = 96. We do the same to the other side. Now we have 96/8 - 65/8 = 31/8. Finally we make this a mixed number. So 31 divided by 8. So you should get 3 7/8.

I hope this helps! :)

HELP 10 POINTS and brainliest! What is the value of X?<br> △MAH∼△WCF .

german

The value of x is 23.

Simply find the scale factor or what was used to dilate △MAH to produce △WCF.

Use the equation copy over the original,

$k = \frac{c}{o} = \frac{15.5}{62}$

Reduce,

$\frac{15.5}{62} = \frac{1}{4} = 0.25$

So our scale factor is ¼ or 0.25

So if we use it and multiply the corresponding side of the missing side with the original we get,

$92 \times \frac{1}{4} = 23$

Therefore 23 is our missing side! !
