Answer:
3x - 4 is the expression that will represent her father's age
Multiply powers with the same base : a^b * a^c = a^(b + c)....so basically, u keep the bases and add the exponents.
dividing powers with the same base : (a^b) / (a^c) = a^(b - c)....so basically, u keep the base and subtract the exponents
raising a power to a power : (a^b)^c = a^(b * c)...so basically, u multiply the exponents
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.
So to get the sides you need to cube them
(192)^1/3---->5.769
(375)^1/3---->7.21125
7.21125-5.769= 1.44225
3^(1/3)= 1.44225
Answer: A
No
Because the two smaller sides added together would equal the larger side, making a line not a triangle.
