Common difference r will be the difference between next two values of number row, so we take e.g. second minus first: r=9.4-6=3.4. You can see, that this value is constant as we go through next pairs of values.
Answer:
about 0.166666
Step-by-step explanation:
i know that the greatest common factor of 4 and 8 is 4 so i divided it by 2/3 to get a rough estimate
Answer: 2x3 + 17x2 + 25x - 50
Step-by-step explanation: Just try to distribute it at every step as follows:
Step 1: Start with the following:
(a + b + c)(d + e)
Step 2: Distribute (d + e) to each of the term in the first parenthesis
a(d + e) + b(d + e) + c(d + e)
Step 3: Distribute d and e to each term:
(ad + ae) + (bd + be) + (cd + ce)
or ad + ae + bd + be + cd + ce without the parentheses.
Step 4: Finally, simplify.
Using the above you should be able to do the following
Step 1: (2x2 + 7x - 10)(x + 5)
Step 2: 2x2(x + 5) + 7x(x + 5) - 10(x + 5)
Step 3: 2x3 + 10x2 + 7x2 + 35x - 10x - 50
Step 4: 2x3 + 17x2 + 25x - 50
X= 2,-2
The Y value is (0,16)
