Answer:
69 years
Step-by-step explanation:
Given that:
Let year of birth = x
This year = 2020
Year of 25th birthday = x + 25
Year of 55th birthday = x + 55
Present age = 2020 - x
Hence,
x + 2020 - (x + 25 + x + 55) + (2020 - x) = 58
x + 2020 - (2x + 80) + (2020 - x) = 58
x + 2020 - 2x - 80 + 2020 - x = 58
-2x + 4040 - 80 = 58
-2x + 3960 = 58
-2x = 58 - 3960
-2x = - 3902
x = 1951
Birth year = 1951
,
Hence, age =
2020 - 1951 = 69 years
Answer:
0, -1
Step-by-step explanation:
zeros occur when 2x^6+2x^5=0
the first way for this to happen would be to set x to 0. both terms would become zero.
the second way is x = -1
first term becomes 2
second becomes -2
these add to zero
7(thousands)
8(hundreds)
5(tens)
4(ones)
.(decimal point)
2(tenths)
0(hundredths)
9(thousandths)
Hope this helps! I would appreciate it if I got brainliest! Thanks! =D
Factors can be multiplied together to get the original number.
For example here are the factors of 66.
1 and 66. 2 and 33. 3 and 22. 6 and 11.
1 multiplied by 66 results in the original number 66.
2 multiplied by 33 results in the original number 66.
3 multiplied by 22 results in the original number 66.
<span>6 multiplied by 11 results in the original number 66.</span>
