A) c=18
0.5c^2 +13=94

0.5c^2 = 81
Square root of both sides to get c alone
0.5c=9
double c to make it just c
c=18

(x-2)^2+1=37
Subtract one from each side
(x-2)^2=36
square root each side
x-2=6

11/98 x 2/99 = ???????
Nutka1998 [239]
All we have to do is multiply the numerator by the other numerator and the denominator by the other denominator.
11•2=22
98•99=9702
They are both even, so we can divide by two with both numbers.
11/4851
4851 can be divided by 11. So we can divide the top and bottom by 11.
1/441 is the product.
