Answer:
-5
Step-by-step explanation:
I think the answer is -5, since if Fiona divided the 3x^2+5x-3 by 3x+2, the remainder would be (x+6)/(3x+2)
If that is a multiplication sign then the answer is 12. But if that is 5x^4 then the answer is -(5x^4-32)
Answer: 30/40, 25/40, 4/40
Step-by-step explanation: Using the Least Common Denominator, I looked at each multiple of each number to determine 40 as the least common denominator, and since we did 4 x 10 to get 40 in the first one, we do 3 x 10 in the first one as well making it 30/40. The second one we did 8 x 5 to get 40, making the numerator (top number) the product of 5 x 5 which is 25 making it 25/40. For the last one, I used 10 x 4 to get 40 meaning I would have to do 1 x 4 to get the numerator (top number) making it 4/40
<em>x₁ = 5</em>
<em>x₂ = - 2</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>x² - 3x - 10 = 0</em>
<em>x² + 2x - 5x - 10 = 0</em>
<em>x(x + 2) - 5(x + 2) = 0</em>
<em>(x - 5)(x + 2) = 0</em>
<em>x - 5 = 0 => x₁ = 5</em>
<em>x + 2 = 0 => x₂ = - 2</em>
<em>Good luck !</em>
<span>Since 1' = 12'', so the scale 1/4'' to 1' is 1/4'' to 12'', or, multiplying both sides by 4, 1 to 48. </span>
<span>Convert all dimensions given from foot/inches to inches, then scale them down, dividing by 48. </span>
10ft 6in=10*12+6=126+6=132 dividing by 48. 132/48=2.75/48=0.0572*1000=57.2 inches
<span>18' 8'' = 18 * 12 + 8 inches = 216 + 8 = 224 inches. Dividing by 48: 224/48 = 4 32/48 = 4 2/3 inch*1000=66.6
