Where would √130 be located on a number line

144 = 12^2
121 = 11^2

so root(130) is between 11 and 12, so is about 11.4 on the number line.

hope this helps :)

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
