Answer:
Well, 3.5 yards + 2.25 = 5.75
Now, just subtract 6.5 - 5.75 = .75
So there will be .75 yards left over . Hope this helps! Pls mark brainliest!
Answer:
2 real solutions
Step-by-step explanation:
To determine the nature of the solutions use the discriminant
Δ = b² - 4ac
• If b² - 4ac > 0 then 2 real solutions
• If b² - 4ac = 0 the 2 real and equal solutions
• If b² - 4ac < 0 then no real solutions
Given
x² + 9x + 20 = 0 ← in standard form
with a = 1, b = 9, c = 20, then
b² - 4ac
= 9² - (4 × 1 × 20 ) = 81 - 80 = 1
Since b² - 4ac > 0 then there are 2 real solutions
4x^3+6x^2-9x+1 is an example
Addition and Subtraction in Scientific Notation. A number written in scientific notation is written as the product of a number between 1 and 10 and a number that is a power of 10. That is, it is written as a quantity whose coefficient is between 1 and 10 and whose base is 10.
