Answer:
12s^2 - s - 20
Step-by-step explanation:
It's simplest form is when it's fully expanded.
To expand: (3s-4)(4s+5)
(3s * 4s) + (3s * 5) + (-4 * 4s) + (-4 * 5)
= 12s^2 + 15s -16s -20
= 12s^2 - s - 20
$3/pound. $12 divided by 4 pounds is $3 per pound.
Answer:
The coefficient of
is 
Step-by-step explanation:
The two expressions are
and
.
The sum of the two expressions is

When we group like terms the expression will be,

When we simplify the expression will now be

The coefficient of
is the constant behind
in the expression.
The coefficient of
is therefore
.

Answer:
Step-by-step explanation:
Given: f(x) = 3(1.7)4x
This can also be looked at as: f(x) = 3 × 1.7 × 4 × x
You can multiply the three values four different ways and they will all be equivalent.
f(x) = (3 × 1.7) × 4 × x = 5.1(4)x
f(x) = 3 × (1.7 × 4) × x = 3(6.8)x
f(x) = 1.7 × (3 × 4) × x = 1.7(12)x
f(x) = 3 × 1.7 × 4 × x = 20.4x
