Answer:
We need to see the expressions given
Step-by-step explanation:
Well, just by looking at the beginning of the problem, Jamelia had made the common mistake of thinking that

(<span>8.4852...)
</span>is equal to

(12)
If you want to estimate a square root like 72, simply find squares that would fit around the number you are looking to find, in our case, 72.
So 9*9 is 81, which is too high and 8*8 is 64, which is too low. So you know that somewhere between those numbers is what your root of 72 is!
Answer:-74
Step-by-step explanation: When you are in the megatives, less is more! So -74 is actually greater then -75
This makes a right triangle with hypotenuse x+2 and legs 10 and x
10²+x²=(x+2)²
100 + x² = x²+4x+4
100=4x+4
4x=96
x=24, the height we are looking for
This is a 45-45-90 triangle and the ratios of the sides are 1 : 1 : sqrt2 where sqrt2 is the length of the hypotenuse ( longest side)
So the measure of x = 12 sqrt2 which is the first choice.
