Answer:
R is 84
Step-by-step explanation:
6 times 14 is 84 and 84 divided by 6 is 14
Answer:
567 mph
Step-by-step explanation:
The speed will actually just be the slope of the line. Slope is change in y-coordinates over change in x-coordinates. We can pick any two points for this; let's just do (1, 567) and (2, 1134).
Slope = (1134 - 567) / (2 - 1) = 567 / 1 = 567
The speed is thus 567 miles/hour.

Step-by-step explanation:
STEP

:
Equation at the end of step 1
(((2 • (x3)) - 3x2) - 23x) + 12
STEP

:
Equation at the end of step
2
:
((2x3 - 3x2) - 23x) + 12
STEP
3
:
Checking for a perfect cube
3.1 2x3-3x2-23x+12 is not a perfect cube
Trying to factor by pulling out :
3.2 Factoring: 2x3-3x2-23x+12
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: -23x+12
Group 2: 2x3-3x2
Pull out from each group separately :
Group 1: (-23x+12) • (1) = (23x-12) • (-1)
Group 2: (2x-3) • (x2)
Bad news !! Factoring by pulling out fails :
The groups have no common factor and can not be added up to form a multiplication.
