It is 3.
You can check this by seeing 3^3 ie. 3x3x3, which comes out as 27.
You can check the cube root on a calculator.

A parabola is open up if a > 0.
The vertex formula:

(h; k) - the coordinates of the vertex

Therefore h = -5 < 0
Answer: B. y = x² + 10x + 24.
I think the answer is b 0.2(20)
- Please find the picture for your triangle.
- We know, area of a ∆ = <u>1/2 × base × height</u>
- Here, base = ( 1 + 7 ) units = <u>8 units</u>
- Height = ( 7 - 1 ) units = <u>6 units</u>
- Therefore, area of the ∆
- = <u>(1/2 × 8 × 6) square units</u>
- = <u>24 square units.</u>
<u>Answer</u><u>:</u>
<em><u>2</u><u>4</u><u> </u><u>square </u></em><em><u>units</u></em>
Hope you can get an idea from it.
Carry on learning.

Answer:
x² - x - 6
Step-by-step explanation:
Step 1: Write expression
(5x² + 2x - 5) - (3x² + 3x + 1)
Step 2: Distribute negative
5x² + 2x - 5 - 3x² - 3x - 1
Step 3: Combine like terms (x²)
2x² + 2x - 5 - 3x - 1
Step 4: Combine like terms (x)
x² - x - 5 - 1
Step 5: Combine like terms (constants)
x² - x - 6
