Answer:

- 7

Step-by-step explanation:

Solve for x

3x + 3 = - 9 ( subtract 3 from both sides )

3x = - 12 ( divide both sides by 3 )

x = - 4

Hence

3x + 5 = (3 × - 4) + 5 = - 12 + 5 = - 7

Simplify the expression: w2 + 7w2 + 8w - 5 + 9 - 2w2

ololo11 [35]

<h3> $6w^2 +8w +4$ is the simplified expression</h3>

<em><u>Solution:</u></em>

Given that,

We have to simplify

$w^2 + 7w^2 + 8w -5+9-2w^2$

We can simplify the above expression by combining the like terms

Like terms are terms that has same variable with same exponent and same or different coefficient

From given,

$w^2 + 7w^2 + 8w -5+9-2w^2$

Group the like terms

$w^2 + 7w^2 -2w^2 + 8w - 5+9\\\\Combine\ the\ like\ terms\\\\6w^2 +8w -5+9\\\\Combine\ the\ constants\\\\6w^2 +8w +4$

Thus the given expression is simplified

If f(1) = 2 and f(n) = f(n − 1)² + 4 then find the value of ƒ (3).

erma4kov [3.2K]

Answer:

f(3) = 68

Step-by-step explanation:

→ f(1) = 2 ⇒ f(2) = f²(2 − 1) + 4

= f²(1) + 4

= 2² + 4

= 8

………………………………………………

→ f(2) = 8 ⇒ f(3) = f²(3 − 1) + 4

= f²(2) + 4

= 8² + 4

= 64 + 4

= 68
