212 tens divided by 10 = - 4442962
Answer:
No Solution
Step-by-step explanation:
If xy = 1, and y is 0, then you can plug in 0 for y. x(0) = 1. You would then need to divide by 0 on both sides, but you cannot do that. Therefore, there is no soultion.
Answer:
Step-by-step explanation:
It would be easier to just show you.
Because we're using variables, I'm going to plug in a random set of numbers to stand for x and y.
(x+y)^2
(2+4)^2=36
vs.
x^2+y^2
2^2+4^2=20
The difference is because, following the order of operations, in the first situation you must first take care of what is in the parenthesis, which means you add x and y together-then you multiply that combined number by the 2nd power. Whereas in the second situation, you multiply x and y by the 2nd power separately, and then add the product of that together. So opposite order. In the first situation you add, then multiply. In the second, you multiply then add.
Answer:
23
Step-by-step explanation:
because there is a 90 degree angle and then the 67 degree angle, and triangle law says that all angles add up to 180.
