Can somebody help with this ‼️

The average rate of change over the interval AC is 8

Step-by-step explanation:

To find the average rate of change, we divide the change in the output value by the change in the input value

The average rate of change over the interval AC is equal to

\frac{f(c)-f(a)}{c-a}

In this problem we have

f(c)=f(2)=18  

f(a)=f(0)=2

c=2

a=0

Substitute

\frac{18-2}{2-0}=8

Step-by-step explanation:

Brainlist me if im right or if it helped :)

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
