Arobin flew rrr meters per second, and a cardinal flew ccc meters per second. the birds flew for ttt seconds. the expression t(r-c)t(r−c)t, left parenthesis, r, minus, c, right parenthesis describes how many more meters the robin flew than the cardinal flew during that time. what does (r-c)(r−c)left parenthesis, r, minus, c, right parenthesis represent in this context?

represents Relative Speed of Robin with respect to Cardinal.

Step-by-step explanation:

Given:

Speed of Robin = 'r' m/s

Speed of cardinal = 'c' m/s

Time flew by birds = 't' seconds.

The expression of distance more robin flew than the cardinal flew =

Now we need to find the   representing in the above expression.

Solution:

Now we can say that When two objects move with speed 'a' and 'b' with same amount of time and in the same direction then we can say that a-b will be the Relative speed of the 'a' with respect to 'b'.

From above expression we can say that;

represents Relative Speed of Robin with respect to Cardinal.

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
