4 1/2 yards
Because 6 (aprons) times 3 = 18
So 18/4 = 4 2/4
Simplified it is 4 1/2
<1 and <7 measures 42 degrees
2 and 5 are alternate interior angles from the figure above
Answer:
-p²q² + 9p² + 4q² + 24pq - 36
General Formulas and Concepts:
<u>Algebra I</u>
- Expanding by FOIL-ing (First Outside Inside Last)
- Combining Like Terms
Step-by-step explanation:
<u>Step 1: Define expression</u>
(p² - 4)(9 - q²) + 24pq
<u>Step 2: Simplify</u>
- Expand by FOIL-ing: 9p² - p²q² - 36 + 4q² + 24pq
- Combine like terms: -p²q² + 9p² + 4q² + 24pq - 36
R(x)= -x2+3x is x=0
s(x)= 2x+1 is x= -1 over 2
(-1-2) (0)
