Ok so a rectangular prism is the same as a rectangular cuboid.
The surface area is all the areas of the faces added together ->
There are three different faces that occur twice
length -> l
width -> w
height ->h
2( l * w ) + 2( l * h ) + ( w * h )
2 ( 10 * 4.5 ) + 2 ( 10 * 8.75 ) + 2 ( 4.5 * 8.75 ) = 343.75 cm2
Therefore it's A
Hope this helps :P
Answer:
Corresponding Angles Theorem
x = -5
Step-by-step explanation:
Since they are corresponding angles, they are equal to each other.
x + 105 = 100
x = -5
Answer:
-1 12⁄13
Step-by-step explanation:
-13x = 25 [Divide by -13]
x = -1 12⁄13
13 is your <em>divisor</em>, which will be your denominator, and the numerator is your <em>remainder</em><em>.</em><em> </em>Since 13 goes into 25 ONCE, 1 gets multiplied by 13 to get 13, then deduct that from 25 to get your remainder of 12. This is where you start putting the pieces together as a mixed number. Then attach the negative because whenever you divide a positive by a negative, you get a negative:
-25⁄13 = -1 12⁄13

Okayuyyyyyyyyyyyyyyyyyyyyyyyyy
<span>This is a 30 - 45 - 105 angled triangle, so the answer would be A.
"</span><span>Largest angle = 105, Middle angle = 45, Smallest angle = 30"</span>
