Answer: x = 7 or x = -8
x² + x - 56 = 0
⇔ x² + 8x - 7x - 56 = 0
⇔ x(x + 8) - 7(x + 8) = 0
⇔ (x - 7)(x + 8) = 0
⇔ x - 7 = 0
or x + 8 = 0
⇔ x = 7 or x = -8
Step-by-step explanation:
See if the distance between the two lines is consistent with a compass.
Make sure the lines intersect at right angles with the corner of a piece of paper.
Measure each of the angles with a straightedge.
There is no way to ensure you have constructed parallel lines.
Answer:
A) Yes, because there is a steady correlation between the 2 variables
B) After 2 hours, they have traveled 100 miles
C) After 5 hours, they traveled 250 miles
D) After 1 Hour, they traveled 50 miles
In conclusion, for every hour of time, they travel a comstant speed of 50 miles.
The answer is 20,106 basically “B”
3.6 divided by 9= 0.4
Answer is 0.4km
