Answer:
C. 106°
Step-by-step explanation:
parallelogram: Opposite angles are congruent.
If a dozen package of spaghetti sauce is priced 3, that means that 12 spaghetti sauces are priced 3, to know the price of an individual spaghetti sauce we need to divide the 3 by 12:
price individual = 3/12
= 0.25
so the price of one spaghetti sauce is 0.25
Answer:
(a) P(1) = 3
(b) P(-2) = 15

Step-by-step explanation:
<u>Step 1: Define</u>
P(x) = x³ + 4x² - 3x + 1
P(1) is x = 1
P(-2) is x = -2
<u>Step 2: Evaluate</u>
<em>P(1)</em>
- Substitute: P(1) = 1³ + 4(1)² - 3(1) + 1
- Exponents: P(1) = 1 + 4(1) - 3(1) + 1
- Multiply: P(1) = 1 + 4 - 3 + 1
- Add: P(1) = 5 - 3 + 1
- Subtract: P(1) = 2 + 1
- Add: P(1) = 3
<em>P(-2)</em>
- Substitute: P(-2) = (-2)³ + 4(-2)² - 3(-2) + 1
- Exponents: P(-2) = -8 + 4(4) - 3(-2) + 1
- Multiply: P(-2) = -8 + 16 + 6 + 1
- Add: P(-2) = 8 + 6 + 1
- Add: P(-2) = 14 + 1
- Add: P(-2) = 15
