Rules to use
Rule 1: x^2 = x*x
Rule 2: (a+b)*(c+d) = a*(c+d)+b*(c+d)
Rule 3: a*(b+c) = a*b+a*c
Using those rules, we get the following
(6+u)^2 = (6+u)*(6+u) ... use rule 1
(6+u)^2 = 6*(6+u)+u*(6+u) ... use rule 2
(6+u)^2 = 6*6+6*u+u*6+u*u ... use rule 3
(6+u)^2 = 36+6u+6u+u^2 ... multiply
(6+u)^2 = u^2+12u+36 ... combine like terms and rearrange
Answer: u^2+12u+36
14 and 15.
the square root of 14 is 196.
the square root of 15 is 225.
200 is in between those 2 numbers
Answer:
1.) True, because it says three times so you know the x belongs there. Also, you have to follow the order of what the problem says.
2.) False, because it is not in the order of how the problem states it.
3.) False, because if you transfer the fraction to a decimal you get 4.333333. It's not valid.
4.) True, because if you do 7 × 3, it equals to 21. So, 21 - 17 = 4. And Jenny is supposed to have 4 quilts.
Hope it helps! :D
