When factoring a trinomial that is in the format ax plus bx plus c the number that is represented by b should be viewed as what?
B. Sum of two numbers
What is the term for the sum of a number and all its descending numbers for example 10 plus 9 plus 8 plus 7 etc?
i dont know but the term for the number times the numbers below it is factorial and is represented by an ! for example: 5!=5x4x3x2x1=120
Which equation represents a line that is parallel to the line represented by the equuation y equals -2x plus 5?
(Y = -2x plus or minus any number) is parallel to (Y = -2x + 5) .
Which two numbers sum to 81 and their difference is 25?
If their difference is 25 then the larger number is the smaller number plus 25. Let the smaller number be x then the larger number is x + 25 → their sum is x + (x + 25) = 81 → 2x = 56 → x = 28 → the two numbers are 28 and 53.
The sum of two numbers is 70The larger number is 4 more than twice the smaller number What is the smaller number?
The larger number is 48, the smaller number is 22. 48 is twice the amount of 22 plus 4. If the smaller number is "x" then the larger number is 2x+4. We know that x+2x+4 =70 which ius the same as saying 3x+4 = 70 or 3x = 70-4 = 66 so x, the smaller number is 66/3 =22
