Answer:
# of granola bars and it's cost.
Step-by-step explanation:
It is asking for the meaning of 2B. Note that inside the question, it states that:
"<em>The price of a granola bar is B dollars</em>".
It also states that:
"<em>Donovan eats </em>2<em> granola bars</em>".
This means that to solve for the total spent on granola bars, you multiply the price (B) with the amount gotten (2 in this case).

Answer:
see below
Step-by-step explanation:
8(n + 2)(n + 4) = 1,144
FOIL
8(n^2 +2n+4n+8) = 1144
Divide each side by 8
8/8(n^2 +2n+4n+8) = 1144/8
(n^2 +2n+4n+8) = 143
Combine like terms
n^2 +6n+8 = 143
Subtract 143 from each side
n^2 +6n+8 -143= 0
Combine like terms
n^2 +6n -135 =0
Factor
What two terms multiply to -135 and add to 6
-9*15 =-135
-9+15 = 6
(n-9) (n+15) =0
Using the zero product property
n-9 =0 n+15=0
n = 9 n=-15
The length cannot be negative so n = -15 cannot be a solution
n =9
y = -4x + 3 this line has slope = -4
parallel lines, slope is the same so slope of new line is also equal -4
passing thru (8, -3)
y = mx + b
b = y - mx
b = -3 - (-4)(8)
b = -3 + 32
b = 29
equation:
y = -4x + 29
