When you simplify the square root of a number, you are looking for factors of the number that are perfect squares that you can remove from under the radical. For example sq root of 8... it's not a perfect square but factors of 8 include 2 x 4... 4 is a perfect square so we can take it out of the radical by taking it's square root. Now you are left with 2* sq root of 2.
For sq root of 48
48 = 12 x 4
12 = 3x4 so we can say 48 = 3x4x4
so... sq root 48 = sq root 3x4x4
we have two 4's under the radical. Sq root x^2 = x so sq root 4^2 is 4
Pull it out from the radical and we are left with 4 * sq root 3
210 because 7th graders washed 12 cars, 8th graders washed 14 cars, 6th graders washed 16 cars. Added all together and multiplied by 5, it equals 210
Answer:
You cant add them so it is probably a trick question.
Step-by-step explanation:
Answer:
term 1 = 5
term 2 = 8
term 3 = 11
term 4 = 14
term 5 = 17
term 6 = 20
term 7 = 23
every time the terms go up, 3 is added
Well your equation would be 40 = 2x + 16 so subtract 16 from both sides and that’s 24=2x then divide both sides by two so the length of the rectangle is 12.
