3n^2 sqrt 5n
hope that helped (:
I interpret the first number to be 89.24, so 84 and 24 hundredths.
The difference would be by how many numbers they differ, so we subtract the smaller from the bigger:
89.24-17=12.24
this would be their difference!

Step-by-step explanation:
<u>Step 1: Define Equation</u>
2x + 10 = -4x - 9
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 4x on both sides: 6x + 10 = -9
- Subtract 10 on both sides: 6x = -19
- Divide 6 on both sides: x = -19/6
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 2(-19/6) + 10 = -4(-19/6) - 9
- Multiply: -19/3 + 10 = 38/3 - 9
- Add/Subtract: 11/3 = 11/3
Here we see that 11/3 does indeed equal 11/3.
∴ x = -19/6 is the solution to the equation.

You could find 5/⅓
by using 5 × 3
Knowing that:
Any number multiplied by 1, gives the number itself.
Dividing any number by itself gives 1.
Writing 5/⅓ as 5/⅓ × 1 doesn't change the value.
Then I can write 5/⅓ as
5/⅓ × (5×3)/(5×3) = 1
This can become
[5×(5×3)] / [(⅓) × (5×3)]
= 75/(15/3)
= 75/5
= 15
or
12/ 3/5
= [12/ (3/5)] × [(5×3)/(5×3)]
= 12×(5×3) / (3/5)×(5×3)
= (12×5×3) / [(3×5×3)/5]
= 180 / (45/5)
= 180 / 9
= 20
Answer:
25
Step-by-step explanation:
In this equation, ax^2+bx+c, b = -1, a = 2, and c = -3. Solving, (-1)^2 - 4(2)(-3) = 1 - (-24), or 25.
