Step-by-step explanation:
<u>Step 1: Define</u>
y² - 7y + 6
y = -3
<u>Step 2: Evaluate</u>
- Substitute in <em>y</em>: (-3)² - 7(-3) + 6
- Exponent: 9 - 7(-3) + 6
- Multiply: 9 + 21 + 6
- Add: 30 + 6
- Add: 36
Answer:
3(x + 1)(x + 2)
Step-by-step explanation:
Given
3x² + 9x + 6 ← factor out 3 from each term
= 3(x² + 3x + 2) ← factor the quadratic
Consider the factors of the constant term (+ 2) which sum to give the coefficient of the x- term (+ 3)
The factors are + 1 and + 2, since
2 × 1 = 2 and 2 + 1 = 3, thus
x² + 3x + 2 = (x + 1)(x + 2) and
3x² + 9x + 6 = 3(x + 1)(x + 2)
It would be 56 because it’s really worked out already
Answer:
%73 1/3
Step-by-step explanation:
First subtract 8 form 30 to find the correct amount of answers. This is 22! Then find how much 22 is of 30 and multiply this by 100 to find the percent. :
22/30*100=73 1/3
