The answer is 28.
<span>(x – 13)(x + 8) = 196
</span>x * x + x * 8 - 13 * x - 13 * 8 = 196
x² + 8x - 13x - 104 = 196
x² - 5x - 104 - 196 = 0
x² - 5x - 300 = 0
The general quadratic formula is ax² + bx + c = 0
In our equation: a = 1, b = -5, c = -300
So, missing length is either:
x1 + 8 = 20 + 8 = 28
or
x2 + 8 = -15 + 8 = -7
Since, length of a triangle cannot be negative, the missing side length is 28
Answer:
x + 46

Step-by-step explanation:
<u>Step 1: Define expression</u>
4(-8x + 5) - (-33x - 26)
<u>Step 2: Simplify</u>
- Distribute: -32x + 20 + 33x + 26
- Combine like terms (x): x + 20 + 26
- Combine like terms (Z): x + 46
1. The fire covered 300
3 days ago
2. Today it covers twice the amount of 3 days ago so 2*300=600 (
)
3. After 3 days from today, it will have covered 2*2*300=1200
4. After 3*2=6 days from today, 2*2*2*300=2400
5. After 3*3=9 days from today, 2*2*2*2*300=4800
6. After 3*4=12 days from today, it will have covered 2*2*2*2*2*300=9600 (
)
7. We can gereralize: After 3*n days from today, it will have covered
