Answer: 
Step-by-step explanation:
For this exercise it is important to remember the following:

Given the following expression:

You can notice that the radicand (the number inside the square root) is negative. Therefore, in order to simplify the expression, you need to follow these steps:
1. Replace
with
and simplify:

2. Descompose 12 into its prime factors:

3. Substitute into the expression:

4. Since
, you can simplify it:

Answer:
No because 16+49 does not equal 121.
Step-by-step explanation:
first make 11 the hypotenuse and 4 and 7 side b and A
Use the pythagorean theorem: A^2+B^2=C^2
4^2+7^2=11^2
16+49=121
4x - y = 1
4x - 1 = y...y = 4x - 1
u have a slope of 4....a y int of ( 0,-1)....an x int of (1/4,0)
Answer:
a) 0.8( 8/10 gives 0.8)
b)0.7( if it was 7/100 it would have been
0.07)
c)3.5( by converting mixed fractions to improper fractions, that is, 3×2+1 and having the same denominator 2… we get 7/2… for the purpose of converting it to decimal, 7×5/2*5= 35/10… by moving one decimal place to the left, we get 3.5)
D) 2.5 ( the same way as c) 5*5/2*5: 25/10 or you can make it to be 5*50/2*50: 250/100 which still gives 2.5)
For this you can just use a calculator and divide 2587.5 by 1150.
You should get $2.25 for the unit price. Hope this helped ^-^
