8(7x+2)= need help to simplify this equation

56x + 16

Step-by-step explanation:

To simplify the expression, we just multiply the number outside the parenthesis - 8 in this problem - by both numbers inside the parenthesis.

So,

8 * 7x = 56x

8 * 2 = 16

56x + 16 is 56x + 16.

This cannot be further simplified.

56x+16

Step-by-step explanation:

7x multiply by 8 and 2 multiply by 8.

- "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."

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
