Answer:
x² - x + 4
General Formulas and Concepts:
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
(4x² - 2x - 3) + (-3x² + x + 7)
<u>Step 2: Simplify</u>
- Combine like terms (x²): x² - 2x - 3 + x + 7
- Combine like terms (x): x² - x - 3 + 7
- Combine like terms (Z): x² - x + 4
The 2nd bottom one is a function
Answer:
I think it is 3?
Step-by-step explanation:
3, -2 ≤ 0
-5, 0 < -2 ≤ 5
3, -2 > 5
The second two lines do not hold true, as -2 is less than 0 and 5, not greater. The only that is true is the first one, but I am not sure that is how you do it.1
Answer:
50.05 cm^2
Step-by-step explanation:
Ok so first lets find the area of the rectangle before finding the attached triangle. You have to imagine a line separating this shape into a triangle and rectangle.
The rectangle's size is 6.5x5.5=35.75 cm^2
The rectangle's size is 11.7-6.5 to get the base length, which is 5.2
The height is 5.5
So it's 5.2*5.5/2=14.3 cm^2
14.3+35.75=50.05 cm^2
