3 × [(2 × 6 - 5) + (8/4)] - 1
= 3 × [(12 - 5) + 2] - 1
= 3 × (7 + 2) - 1
= 3 × 9 - 1
= 27 - 1
= 26

If we want to compute $f(2+h)$ , we have to substitute every occurrence of $x$ with $2+h$ in the definition of the function:

$f(x)=x^2-11x \implies f(2+h) = (2+h)^2-11(2+h) = 4+4h+h^2-22-11h = h^2-7h-18$

Similarly, computing $f(2)$ means to substitute the input with 2:

$f(x)=x^2-11x \implies f(2) = 2^2-11\cdot 2 = 4-22 = -18$

So, we have

$f(2+h) - f(2) = h^2-7h-18 - (-18) = h^2-7h$

And finally

$\dfrac{f(2+h)-f(2)}{h} = \dfrac{h^2-7h}{h} = h-7$

Gabrielles age is three times mikhals age. The sum of their ages is 44. What is MIkhails age?

Ymorist [56]

Soln:
Let mikhale's age be X
Gabrielle's age be 3X
Sum of their ages is 44

To find,
their ages.

X+3X=44
4X=44
X=44/4
X=11

mikhale's age= 11

Gabrielle's age = 3x11=33

Sum of their ages 44

Thus we have got their ages.Gabrielle's age is 33 and Mikhale's age is 11.
