(3 + 6i)(3 + 7i)
FOIL: First, Outside, Inside, and Last
3 x 3 = 9
3 x 7i = 21i
6i x 3 = 18i
6i x 71= 42i
9 + 21I + 18I + 42I = 9 + 81I
a = 9
B = 81I
When you multiply 3.41 times 2 you get 6.82
When you subtract the exponent β to get ∫og ∨∨3
you get ₉ as your number because ₙₓ + quadratic formula = ᵇ⁽₊₊⁾
Answer:
- The baby grew 1 3/16 inches
Step-by-step explanation:
A new baby grew:
- 3/4 of an inch in June,
- 7/16 of an inch in July.
Total inches during two months:
- 3/4 + 7/16 = <em>Fractions with different denominators</em>
- 3*4/(4*4) + 7/16 = <em> Multiply the first fraction by 4</em>
- 12/16 + 7/16 = <em>Add numerators</em>
- 19/16 = <em>Numerator is greater than denominator</em>
- (16 + 3)/16 = <em>Convert to mixed fraction</em>
- 16/16 + 3/16 =
- 1 + 3/16 =
- 1 3/16 <em>Answer</em>
Answer:
f(x) = 3x² - 6x + 12
General Formulas and Concepts:
- Order of Operations: BPEMDAS
- Expand by FOIL (First Outside Inside Last)
- Standard Form: f(x) = ax² + bx + c
- Vertex Form: f(x) = a(bx + c)² + d
Step-by-step explanation:
<u>Step 1: Define function</u>
Vertex Form: f(x) = 3(x - 1)² + 9
<u>Step 2: Find Standard Form</u>
- Expand by FOILing: f(x) = 3(x² - 2x + 1) + 9
- Distribute 3: f(x) = 3x² - 6x + 3 + 9
- Combine like terms (constants): f(x) = 3x² - 6x + 12
