The answer is -3
You use the formula y1-y2
———
x1-x2
-1 and 8 are your y’s
1 and -2 are your x’s
Your equation should look like this
-1-8 -9
—— = —— = -3
1-(-2) 3
I plugged the y’s and x’s into the formula.
I hope this helps!!
Distance formula : d = sqrt (x2 - x1)^2 + (y2 - y1)^2
(-5,-1)(-1,12)
d = sqrt (-1-(-5)^2 + (12 - (-1)^2
d = sqrt (-1 + 5)^2 + (12 + 1)^2
d = sqrt (4^2) + (13^2)
d = sqrt (16 + 169)
d = sqrt 185
d = 13.60 <==
Area of the square = 72.25
Side = 8.5 in
Perimeter = 4 × side
Perimeter = 4 × 8.5 in
Perimeter = 34 in
Answer:
3(x+2)=12
Step-by-step explanation:
Answer:
Step-by-step explanation:
Add 37 to both sides (to combine like terms):
3(4x + 1)^2 = 42
Reduce this by dividing both sides by 3:
(4x + 1)^2 = 14
Taking the square root of both sides results in:
4x + 1 = ± √14, or
4x = -1 ± √14
Solve for x by dividing both sides by 4:
-1 ± √14
x = ----------------
4
