Breadth=B=5in
Height=H=7in
Volume=V=70in^3
Length=L

$\\ \sf\longmapsto V=LBH$

$\\ \sf\longmapsto 5(7)L=70$

$\\ \sf\longmapsto 35L=70$

$\\ \sf\longmapsto L=2in$

Answer:

2 in

Step-by-step explanation:

<u>Given:</u>

w = 5 in
h = 7 in
V = 70 in³

<u>The volume equation:</u>

V = lwh

<u>Find the value of l:</u>

l = V/wh
l = 70/(5*7)
l = 2 in

Given g(x)=x^2 and h(x)= x-3 find (g ∘ h)(x)

DerKrebs [107]

Answer:

<h2>(g ∘ h)(x) = x² - 6x + 9</h2>

Step-by-step explanation:

g(x) = x²

h(x) = x - 3

To find (g ∘ h)(x) substitute h(x) into g(x) that's for every x in g(x) replace it with h(x)

That's

(g ∘ h)(x) = ( x - 3)²

= x² - 3x - 3x + 9

We have the final answer as

<h3>(g ∘ h)(x) = x² - 6x + 9</h3>

Hope this helps you
