Answer:
(x + 4) × (2x - 5)
Step-by-step explanation:
- Begin by writing 3x as a difference
- 2x^2 + 8x - 5x - 20
- Factor out 2x from the expression
- 2x × (x + 4) - 5x - 20
- Factor out -5 from the expression
- 2x × (x + 4) - 5 (x + 4)
- Factor out x + 4 from the expression
- (x + 4) × (2x - 5)

Answer:
Two straight lines with slopes m and m' are parallel when m = m'
Two straight lines with slopes m and m' are perpendicular when m × m' = - 1.
Step-by-step explanation:
Let us assume that the two non-vertical lines in the slope-intercept form are
y = mx + c ........... (1) and
y = m'x + c' ............ (2)
If those two lines are parallel then we can say the slope of them will be the same i.e. m = m'
Now, if given two straight lines (1) and (2) are perpendicular to each other and neither of them is parallel to the axes, then we can write m × m' = - 1. (Answer)
the starting amount would be the 550, because it doesn't have a variable assigned to it.
change per week is 20 since it is being multiplied by the number of weeks
