Let g(x) = x + 2
f(g(x)) = 2x^2 - x + 3
= 2(x^2 - x/2 + 3/2)
=2 (x^2 + 4x + 4) - 9x - 5
=2 (x+2)^2 - 9(x+5/9)
=2 (x + 2)^2 - 9 (x + 2) +13
f(x) = 2x^2 -9x + 13

What is the following quotient? sqrt6+sqrt11/sqrt5+sqrt3​
Gnoma [55]

Answer:

√30-√18+√55-√33/2

Step-by-step explanation:

What is the following quotient? sqrt6+sqrt11/sqrt5+sqrt3​

Given the expression

√6+√11/√5+√3

Rationalize

√6+√11/√5+√3 × √5-√3/√5-√3

= √30-√18+√55-√33/√25-√9

= √30-√18+√55-√33 /5-3

= √30-√18+√55-√33/2

This gives the required quotient

Solve the inequality 4(n-3)- 6 &gt; 18
Sonbull [250]

Answer:

n>9

Step-by-step explanation:

4(n-3)- 6 > 18

To solve this inequality we need to remove the parenthesis

distribute 4 inside the parenthesis

4n -12 - 6 > 18

Now combine like terms

4n - 18 > 18

We need to isolate 'n', so we add 18 on both sides

4n > 36

Now divide both sides by 4

n > 9

So the value of n is greater than 9
