For this case we must factor the following expression:
To factor, we must find two numbers that when added together give -7 and when multiplied by -10.
It is observed that there are not two whole numbers that comply with the aforementioned.
Thus, the following equation applies:
Where:
We replace:
So, the roots are:
Answer:
1/8 why? because 1/2 for the first head. times 1/2 for the second head. times 1/2 for the third head
Step-by-step explanation:
1st digit is 1 number (1)
2nd digit is (3,4,5) so it's 3 numbers
third digit is (6,7,8,9) is it's 4 numbers
last 7 digits is 10 (0,1,2,3,4,5,6,7,8,9)
multiply
1*3*4*10=120
so answer is 120 phone numbers
L x w x h = volume
volume = 5 x 5 x 5 = 125 cm ^ 3
