You have to subtract the largest number from the smallest and you get your range. Which would be 7.5-2.1 equals 5.4 which is b.
Answer:
84 in²
Step-by-step explanation:
(15+6)0.5 * 8 = 21(0.5) * 8 = 10.5 * 8 = 84
The greatest common factor: 20x^6y 40x^4y^2 10x^5y^5 is 10x^4y.
20x^6y = 10x^4y*2x^2
40x^4y^2 = 10x^4y*4y
10x^5y^5 = 10x^4y*y^4
These are the steps. Just follow the numbers on the left hand side. Hopes this helps. The answer is -3.
