Using the Pythagorean theorem:
x^2 + (x-2)^2 = (√20)^2
Simplify the right side:
x^2 + (x-2)^2 = 20
Subtract 20 from both sides:
x^2 + (x-2)^2 - 20 = 0
Factor:
(x-4)(x+2) = 0
Solve for each x:
x = 4 and x = -2
The side cant be a negative value, so the answer would be x = 4
The answer is B.
Answer:
<em>Answer B</em>
Step-by-step explanation:
<u>Fractions on the Number Line</u>
The number line contains an ordered sequence of the numbers, where the smaller numbers are at the left of the greater numbers.
This means -3 is to the left of -2, which is to the left of -1.
Number -2 1/4 lies between -2 and -3.
The only point lying on that interval is B.
Answer B
Answer: 
Step-by-step explanation:
First you put it in to y= mx+b form.

Then you subtract 34 from both sides

Then you divide 8 from both sides
Leaving you with

4/15 = 0.267
8/25 = 0.32
0.267/0.32 = 0.834375
