Dylan has a fish tank at home. He knows its height, h, is one inch less than twice the width, w, and the length, l, of the fish

pickupchik [31]

The right answer is: The binomial expression 2w + 6 represents the length of the fish tank.

Dylan has a fish tank, so we assume that this tank is a cube. In this way, the volume of the tank is given by this expression:

$V = w.h.l$

Where:

h: height

w: width

l: length

We know the following things:

FIRST. He knows its height, h, is one inch less than twice the width, w.

This can be expressed as the following equation:

$h=2w-1$

SECOND. The length, l, of the fish tank is seven inches longer than the height.

We can express this statement as follows:

$l=h+7 \\ \\ \therefore l=2w-1+7 \\ \\ \therefore l=2w+6$

By substituting $h \ and \ l$ in $V$ :

$V=w.h.l \\ \\ \therefore V=w(2w-1)(2w+6) \\ \\ \therefore V=w(4w^2-12w-2w-6) \\ \\ \therefore \boxed{V=4w^3-14w^2-6w}$

You are arranging a meeting for 56 people. You want 8 people at each table. How many tables do you need?

we can do this by dividing

56 ÷ 8 = 7

you will need 7 tables

The function for the cost of materials to make a shirt is f(x) = five sixths x + 5, where x is the number of shirts. The functio

$\bf \begin{cases}
f(x)=\cfrac{5}{6}x+5\\\\
g(x)=5x+6
\end{cases}\qquad g(\ f(x)\ )=5[\ f(x)\ ]+6
\\\\\\
f(18)=\cfrac{5}{6}(18)+5\implies f(18)=\cfrac{5\cdot 18}{6}+5\implies f(18)=15+5
\\\\\\
\boxed{f(18)=20}\\\\
-------------------------------\\\\
g(\ f(18)\ )=5[\ f(18)\ ]+6\implies g(\ f(18)\ )=5[\ 20\ ]+6
\\\\\\
g(\ f(18)\ )=106$
