You need to find the total surface area of the rectangular prism. The top and bottom are 8(6), which equals 48. Since we want both the top and bottom, multiple 48 by 2 to get 96. The we need to calculate the remaining 4 sides. Two of them are 15(6), which is 90. Again, multiply by two since there’s two of those sixes to get 180. Finally, the last two sides are 15(8), which is 120. Add all of these numbers together to get 96+180+120=396. So she will need 396 cm^2 of fabric.
Answer:
x=3
Step-by-step explanation:
since they give you y this is a very simple problem
simply replace y with -3 and get
3x+(-3)=6
adding a negative number is the same as subtracting a positive number
3x-3=6
add 3 on both sides
3x=9
divide by 3 on both sides
x=3
Answer:
E.) 1
Step-by-step explanation:
Firstly we will solve for L.H.S.
L.H.S. =
Since we know that is the inverse of 
.
So we can say that;
Now For R.H.S.
Since we can rewrite 
as 
.
Now we can say that the R.H.S. is;
Now we add the fraction and get;
Now according to trigonometric identity;
So, 
Here,
and = 
<em> </em>
L.H.S. = R.H.S.
Hence 
Answer:
100 litres
Step-by-step explanation:
As it says, the second one even it surveys fewer gamers, but their yearly income is verified, which are accurate, unlike the first one, where the gamers only report their income, which is not 100% true. some people may fake the number. therefore, the second one is more accurate and believable.
