First u have to find the area 11x3=33, 3x1=3, 3x2=6 sum=42
I think 306? Not completely sure! Hope this helps!!
Answer:

Step-by-step explanation:
We are given that
Distance traveled by a toy car

Where t>3
Time taken by car =t-3 seconds
We have to find the expression which represents the speed of the toy car.
We know that

Using the formula




Hence, the expression which represents the speed of the toy car

The decimal of 2.1 is greater than 2.0 but less than 2.42
(3,4)(5,16)
slope = (16 - 4) / (5 - 3) = 12/2 = 6
y = mx + b
slope(m) = 6
use either of ur points (3,4)...x = 3 and y = 4
sub and find b, the y int
4 = 6(3) + b
4 = 18 + b
4 - 18 = b
-14 = b
so ur equation is : y = 6x - 14
