If f(x) =x/4 - 3 and g(x) = 4x2 + 2x - 4, find (f +g)(x).

Iteru [2.4K]

Answer:

4x^2 +9x/4 -7

Step-by-step explanation:

f(x) =x/4 - 3

g(x) = 4x^2 + 2x - 4

(f +g)(x) = x/4 - 3 + 4x^2 + 2x - 4

= 4x^2 + 8x/4+x/4 -7

= 4x^2 +9x/4 -7

HURRY PLEASE<br> e/2=3 <br> e=___ ?

Stolb23 [73]

Answer:

Step-by-step explanation:

To solve for e, it must be <em>alone</em> on one side of the equation

Your equation is:

e/2 = 3

To get rid of the divided by 2, you multiply both sides by 2 since multiplication is the opposite of divison.

So:

e/2 = 3

[Multiply both sides by 2]

e = 6

So, e = 6

I hope this helps! :)

A submarine at a depth of -2 2/3 feet descended 5 1/2 feet. How many feet must the submarine rise to reach the surface? Explain

vladimir2022 [97]

Original position of the submarine below the Surface = -2 2/3= -8/3

Submarine at a depth of -2 2/3 feet descended by 5 1/2 feet.

So new position of the Submarine = $\frac{-8}{3}-\frac{11}{2}\\\\ = \frac {-16 - 33}{2}\\\\ = \frac{-49}{6}$

To Reach the surface submarine must rise = 0-(-49/6)

As seen from the equation the two negative sign [(-)(-)] will change into a positive sign.

At the surface the position of the submarine = +49/6 feet

Yuri [45]

P = 4(2x^2 + 1)...when x = 3.5
P = 4(2(3.5^2) + 1
P = 4(2(12.25) + 1
P = 4(24.5 + 1)
P = 4(25.5)
P = 102 inches <===
