2+11x+121=x+96 is rearranged as: x^2+11x+121-x-96. => x^2 +10x +25, which is like ax^2+bx+c. So D = b^2-4ac = (10^2-4*1*25) = 0. So the discriminant of the given equation is 0.
Answer:
2. and 3. are the answers as the graph doesn't go negative after or at the second side
5(k+4)-2k
Multiply the k and the 4 by 5
Now you have 5k+20-2k
Minus 2k from 5k
Now you have 3k+ 20 that’s the answer
2(3+d-1)
Multiply 3, d, and 1 by 2
Now you have 6+2d-2
Minus 2 from 6
Now you have 4+2d that’s the answe
Hello there! And welcome to brainly . com! Your number one asking and answering site.
Answer: No.
Why?
The said decimal is a string of numbers, but does not have the same number repeated over and over again, nor does it have a triple dot after it. Thus, it is not repeating.
Hope this helped you, and have a great day! ♥
If it is 1/40 as the ratio then multiple the top by 12 and bottom by 12 to get 480 miles
