Simplify the expression 3x(x – 12x) + 3x2^ – 2(x – 2)2^. Which statements are true about the process and simplified product? Check all that apply.
• the term -2(x-2)2^ is simplified first by squaring the expression x-2.
• The simplified product is a binomial.
• after multiplying the like terms are combined by adding and subtracting.
•The parentheses are eliminated through multiplication.
• The final simplified product is -28x2^ + 8x - 8.

maybe - definition of supplementary angles. im not sure. sorry

step-by-step explanation:

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
