What number should be added to 8 to get a sum of -8?
0
What is the answer to the sum 0 - -8 equals?
8
Why is the sum of a rational number and it's opposite always equal to 0?
Because the opposite of 8 for example is -8 and 8+(-8) = 0
What would the sum of opposites be?
The sum of a number and its opposite would be zero. Example: 8 + -8 (since it's easier to not use double signs i'll write it this way) 8 - 8 = 0.
If the sum of a number and its square is 72 then what is the number?
x+x^2=72x^2 +x -72=0 (x+9)(x-8)=0 x=-9 or x=8
Their sum is 0, and the product is -64 what is the value of both number?
The nos. Are 8 and -8 Sum of the nos. 8+(-8)=0 Product of the nos. 8 × (-8) = -64
What number should be added to 8 to get a sum of -8?
0
Is eight times the sum of a number and -192 is 64?
Not necessarily. If the number is 0, then the sum of 8 times the number and -192 is -192.
What is the smallest number after 8000 divisible by 9?
That is 8001. For a number is divisible by 9, the digits must sum up to 9 (or a multiple of 9). So for 8000, the digits sum to 8 [8 + 0 + 0 + 0 = 8]. So you're only 1 away from 9 [8 + 0 + 0 + 1 = 9]
What is the answer to the sum 0 - -8 equals?
8
Why is the sum of a rational number and it's opposite always equal to 0?
Because the opposite of 8 for example is -8 and 8+(-8) = 0
The sum of any number and 0 is the number?
The sum of any number and 0 is the original number.
What would the sum of opposites be?
The sum of a number and its opposite would be zero. Example: 8 + -8 (since it's easier to not use double signs i'll write it this way) 8 - 8 = 0.
If the sum of a number and its square is 72 then what is the number?
x+x^2=72x^2 +x -72=0 (x+9)(x-8)=0 x=-9 or x=8
What is 8-0?
8
What is the sum of angles of an 8 sided octagon?
0 = (n-2) * 1800/nwhere, n--> number of sides of a regular polygon0--> each angle of a regular polygonfor an octagon--> 0 = (8-2)*1800/8 = 1350therefore sum of angles = 1350 * 8 = 10800
What is the additive inverse of the complex number 8 plus 3i?
To form the additive inverse, negate all parts of the complex number → 8 + 3i → -8 - 3i The sum of a number and its additive inverse is 0: (8 + 3i) + (-8 - 3i) = (8 + -8) + (3 + -3)i = (8 - 8) + (3 - 3)i = 0 + 0i = 0.
