Answer: it is (A).
Step-by-step explanation: hope this helps.
The quadratic equation x² - 5x - 4 = 0 has two real roots as 41 > 0.
<h3>What is a quadratic equation?</h3>
A quadratic equation is an algebraic equation of degree two.
We know in a quadratic equation ax² + bx + c = 0, The discriminant D is b² - 4ac.
If D > 0 the quadratic equation has two real roots.
If D = 0 the quadratic equation has one real root.
If D < 0 the quadratic equation has no real roots.
∴ In x² - 5x - 4 = 0,
Discriminant D is b² - 4ac.
= (-5)² - 4.1.(-4).
= 25 + 16.
= 41.
∴ D > 0 and the quadratic equation has two real roots.

The degrees stay the same.
Multiply the decimal by 60
0.39 x 60 = 23.4
Now take the decimal bit and mulitply by 60 to get the seconds.
0.4 x 60 = 24.
So the answer is: 40 degrees, 23 minutes, 24 seconds.
Answer:
Therefore, the resulting expression for the price Genevieve will pay
will be:
Step-by-step Explanation:
Let the original cost of a laptop = p dollars
- As the laptop on sale for $100 off
- Genevieve also has a 15% off coupon
So, subtract the $100 and 15% off coupon (15% off on original 'p' cost)
The resulting expression for the price Genevieve will pay can be computed as:
∵
Therefore, the resulting expression for the price Genevieve will pay
will be:

Answer:
Equation : x + 1 + 3x = 7
Miles Lissette biked : 3/2 miles
Step-by-step explanation:
<em>Step 1: Determine the total number of miles biked.</em>
From my understanding. 7 miles is the total number of miles biked by both.
<em>Step 2: Assume the values</em>
Miles Lissette biked = x
Miles Shane biked = 1 + 3x
<em>Step 3: Add miles biked by Lissette and Shane which will be equal to total miles. </em>
Equation for miles Lissette biked: x + 1 + 3x = 7
4x + 1 = 7
x = 6/4
<em>Step 4: Simplify</em>
x = 6/4
x = 3/2
Therefore, the equation for miles Lissette biked is x + 1 + 3x = 7 and Lissete biked for 3/2 miles.
