Problem 2
Answer: choice B
Add up the functions to get
M(s) + L(s) = (225+0.65s) + (54 + 1.15s)
M(s) + L(s) = (225+54) + (0.65s+1.15s)
M(s) + L(s) = 279 + 1.80s

if you are given a question like this u will leave it like that because maybe the question is wrong
Answer: 4x² + 4xy - 3y²
Concept:
When encountering questions that ask for simplifying algebraic expressions, using the FOIL method would be easier:
- <u>First</u>, which means multiplying the first terms together;
- <u>Outer</u>, which means that we multiply the outermost terms when the binomials are placed side by side;
- <u>Inner</u>, which means multiply the innermost terms together;
- <u>Last</u>, which means that we multiply the last term in each binomial together.
Solve:
<u>Given</u>
(2x - y) (2x + 3y)
<u>Expand parentheses and apply the FOIL method</u>
=4x² + 6xy - 2xy - 3y²
<u>Combine like terms</u>
=4x² + (6xy - 2xy) - 3y²
=
