Answer:
80 yd^2
Step-by-step explanation:
Since the formula for squares is s^2, we can use this to set up an equation, which is
s^2=400
If we square root this, we get
s=20
The perimeter formula for a square is 4s, so if we plug in, we end up with 80 yd^2
Answer:
2k
Step-by-step explanation:
3k and -k are both like terms, so you can combine them. Adding opposite signs works in the same way as subtraction, so you can rewrite the expression as 3k-k, which is 2k.
Then the answer is 17 minus 8 times the square root of 2, or 5.68629
Option C: 
is the right answer
Step-by-step explanation:
Given points are:
(x1,y1) = (-1,2)
(x2,y2) = (3,4)
First of all, the slope has to be found
The slope-intercept form of line is:
Putting the value of m
Putting (3,4) in equation
Putting the value of b
Hence,
Option C: is the right answer
