Answer:
x = -4/5 and x = 1
Step-by-step explanation:
5x^2 - x - 4 = 0
Factor out x from the expression.
x (5x +4) - 5x -4 = 0
Factor out the negative sign from the expression.
x (5x + 4) - (5x+4) = 0
Factor out 5x + 4 from the expression.
(5x +4) x (x-1) = 0
When the product of factors equal 0, that means atleast one factor is 0.
5x+4= 0
x-1 = 0
Solve the equation for x.
5x + 4 = 0
Minus 4 from both sides.
5x = -4
Divide by 5.
x = -4/5
Solve the equation for x.
x - 1 = 0
Add one to both sides.
x = 1
Therefore, x = -4/5 and x = 1.
Answer:
All of them are parallel
Step-by-step explanation:
This is due to the all of the 90 degree angle which would make the rest of the line a would be another 90 degree angle Which are found on every line. This would make all of the lines parallel because it is a total of 180 degrees.
Step-by-step explanation:
(4.4)^2 = b^2 + (2)^2
(4.4)^2 - (2)^2 = b^2
root 19.36 - 4 = b
root 15.36 = b
8 root 6/5 (8 root 6 divided by 5) = b
Area of the parallelogram = b × h
= (8 root 6 divided by 5) × 4.4
= 17.24440779 cm^2
B because -3 times -2 is positive six.
Answer: Yes
