Step-by-step explanation: since im in midddle school and you probaly wouldnt want to get an answer from a child i can assure you this is correct and to get my answer i just added some of the numbers with its exponets

Answer: 14</h3>
Explanation:
Pick two columns from the table to form the (x,y) points.
I'll pick the last two columns, since everything is positive here. So we have the points (2, 17) and (4, 45)
Apply the slope formula to those points
m = (y2 - y1)/(x2 - x1)
m = (45 - 17)/(4 - 2)
m = (28)/(2)
m = 14
The rate of change is 14.
Answer:
4 2/3 = 12/3 + 2/3 = 14/3
11 1/12 = 132/12 + 1/12 = 133/12
then you have to change the denomiators so that they are the same. you can multiply 14/3 times 4/4 and the the denomiators will both be 12.
14/3 x 4/4 = 56/12
133/12 + 56/12 = 189/12
15 9/12 = 15 3/4

Answer:
(x - 7)(x + 3) = 0
Step-by-step explanation:
To factorise the quadratic
Consider the factors of the constant term (- 21) which sum to give the coefficient of the x- term (- 4)
The factors are - 7 and + 3, since
- 7 × 3 = - 21 and - 7 + 3 = - 4, thus
(x - 7)(x + 3) = 0 ← in factored form
