General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
- Function Notation
- Combining Like Terms
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 3x + 5
g(x) = x²
(f - g)(x) is f(x) - g(x)
<u>Step 2: Find (f - g)(x)</u>
- Substitute: (f - g)(x) = 3x + 5 - x²
- Rewrite: (f - g)(x) = -x² + 3x + 5

Answer:
Oldi is best value
Step-by-step explanation:
<u>Lidal</u>
8 rolls for £3.76
72 rolls for £3.76*9= £33.84
<u>Oldi</u>
9 rolls for £4.14
72 rolls for £4.14*8= £33.12
Oldi offers better price for 72 rolls
Using basic math we will eventually come with an answer of 9.
Marcia: 1.5 meters tall / 2 meters long shadow
Building: unknown height / 24 meters long shadow
So 1.5/2 = x/24
You can cross multiply: 2x = 36
Divide: x = 18
So your answer is C).
