Answer:
A
Step-by-step explanation:
x^2 - 4x +3
(x - 1)(x-3)
x = 1, x = 3
Answer:
1/10
Step-by-step explanation:
The probability of flipping heads is 1 out of 2 or 1/2
The probability of getting a 5 on the spinner is 1/5
The probability of getting both is 1/2 * 1/5 = 1/10
You should try this out by listing all the ways this can happen.

There are 10 ways of this problem giving results. Only 1 of them is correct.
The answer is Difference of Cubes.
Difference of cubes is a³ - b³.
27 can be written as 3³ (= 3 × 3 × 3 = 27). So, a = 3.
8 can be written as 2³ (= 2 × 2 × 2 = 8). So, b = 2.
Difference of cubes can be expressed as:
a³ - b³ = (a - b)(a² + ab + b²)
⇒ 3³ - 2³ = (3 - 2)(3² + 3×2 + 2²) = 1 × (9 + 6 + 4) = 1 × 19 = 19
⇒ 27 - 8 = 19
Y=4x-1 because it can be the only one
Part A:
23 + 13x ≤ 81
Part B:
23 + 13x ≤ 81
<u>-23 </u> <u>-23</u>
13x ≤ 58
<u>/13 </u> <u>/13</u>
x ≤ 4.46
Part C:
This means that you can have 4 cheeseburgers while keeping the fat under 81 grams.
