Answer:
Step-by-step explanation:
Distributive property:
a(b-c) = a*b + a*-c = ab-ac
13.- 11(s+9) = 11*s + 11+9 = 11s+99
14.- -21(x-7) = -21*x -21*-7 = -21x + 147
15.- 13(20-a) = 13*20 + 13*-a = -13a + 260
16.- -8(17+b) = -8*17 -8*b = -8b - 136
17.- (r+1.68)(-0.1) = -0.1(r+1.68) = -0.1*r - 0.1*1.68 = -0.1r - 0.168
18.- 3.25(5.02-t) = 3.25*5.02 + 3.25*-t = -3.25t + 16.315
Answer:
Multiplying Integers can be used in the real world in a lot of ways because of their positive and negative. The Positive and Negative will be used as like what you have to owe in money/cash or what you have.

Answer:
R = 5500t
Step-by-step explanation:
The estimated monthly revenue is said to be 5500 per month. Then for t months, the revenue R will be ...
R = 5500t
_____
<em>Additional comment</em>
We expect costs to be C = 3200t, so profit is ...
P = R -C
P = 5500t -3200t
P = 2300t
At that rate, it will be 50 months before enough profit is earned to pay for the initial cost of the store.

Step-by-step explanation:
The length of its diagonal in terms of r and s is √r² + s²
In order to get the length of the diagonal of a triangle, we will use the Pythagoras theorem:
Pythagoras theorem states that the sum of the square of the diagonal is equal to the sum of the square of the other two sides.
Given the following
Length = r feet
width = s feet
The diagonal "l" will be expressed as;
l² = r² + s²
Take the square root of both sides
√l² = √r² + s²
l = √r² + s²
Hence the length of its diagonal in terms of r and s is √r² + s²
