Answer:
Completing the square we have
Step-by-step explanation:
we have to divide the coefficient of x by half, and then raise it to the square, that number is added and subtracted at the same time
later we can write
we know
so we have
abs(x+8)=
we have
x+8=
x+8=
finally we have
By using dimensional analysis, we can find the km/hr quickly
He travels at about 90.91km/hr
Answer:
72,90
Step-by-step explanation:
Since 9 is the biggest number so list multiples of 9 between 55- 101 range.
Which are 63, 72, 81, 90, 99. Any number that is a multiple of 9 is a multiple of 3 because 3x 3 = 9. 9 is a multiple of 3.
Any even number is a multiple of 2.
Only 72 and 90 are even numbers.
So 72 and 90 are numbers divisible by 2, 3, 9.
Answer:
The answer is D
Step-by-step explanation:
If you use. MAD then all you have to do is multiply add then divide so the 1/4 +1/16 +. 1/64 + 1/256 = 1/3 so round it and. its 1/3 (1/4)
The consecutive angles are
Angle x
And
Angle z
