Step-by-step explanation:
Answer:
the area of the actual living room floor is 24 square feet.
Step-by-step explanation:
Answer:
-4/3
Step-by-step explanation:
- since the both lines are perpendicular the product of their slopes equals -1
- let m be the slope of the red line
- m*a = -1
- m = -1/a
- a = (8-5)/(0-(-4)) = 3/4
- so m = -4/3
Answer:
1/2.
Step-by-step explanation:
There seem to be a couple prominent points on the line. We can use two of them to find the slope.
(0, 75)
(30, 90)
(90 - 75) / (30 - 0) = 15 / 30 = 3 / 6 = 1/2.
Hope this helps!
Answer:
x = 0 or x = 1/2 and x = -1 for the second equation
Step-by-step explanation:
Solve for x:
4 x^2 - 2 x = 0
Factor x and constant terms from the left hand side:
2 x (2 x - 1) = 0
Divide both sides by 2:
x (2 x - 1) = 0
Split into two equations:
x = 0 or 2 x - 1 = 0
Add 1 to both sides:
x = 0 or 2 x = 1
Divide both sides by 2:
Answer: x = 0 or x = 1/2
_______________________________
Solve for x:
x^2 + 2 x + 1 = 0
Write the left hand side as a square:
(x + 1)^2 = 0
Take the square root of both sides:
x + 1 = 0
Subtract 1 from both sides:
Answer: x = -1
