The area of a square is the length of the side squared. 13^2 = 169
The area of a square with a side length of 13 feet is 169 feet.
Hope this helps =)
If a root is a+√b then another is a-√b because of quadatic formula
r2=1-√5
Answer:
Ryan 40
Stacy 17
Step-by-step explanation:
x -----> Stacy
x + 23 -----> Ryan
x + 6 Stacy
x + 23 + 6 Ryan
x + 29 Ryan
x + 29 = 2(x + 6)
x + 29 = 2x + 12
x - 2x = 12 - 29
-x = - 17
x = 17 Stacy
x + 23
17 + 23
40 Ryan
Answer:
y=mx+b is slope-intercept form
where m is the slope and b is the y intercept.
Since the line crosses the y axis at 0,0 the intercept is +0 or just nothing.
now all we need to do is find the slope
to do that just go from the y intercept (the first point) y units up and x units over untill u cross at the next point. for examples from (0, 0) to (1, 8)-the next point- i need to go up 8 units up and 1 unit over. this is described as rise over run and that is your slope 8/1 rise/run. rise is how many units i go up (or down) from the y intercept until the next point that lies on the line and run is how far i need to go over from how many units i just went up. If u continue to go 8 up and 1 over from each point u will see that u get a point lying of the line. This is why 8/1 is your slope
8/1 is the slope and 0,0 is your y intercept so we put nothing
the equation is y=8x

Answer:
-14
Step-by-step explanation:
difference between -20 and -5 = 15
15 x 2/5 = 30/5 = 6
-20 + 6 = -14
