We are asked to find unknown or the missing number to complete the polynomial given in the problem which is x² + ?x -49. First, let us equate the number to be equal to zero such as it would become x² + ?x - 49 = 0. Next, we need to find the factors such that it would produce a difference of squares and these two factors are a = +7 and b = -7. Hence, the complete solution is shown below:
(x + 7) (x-7) = 0
perform distribution and multiplication of terms such as shown below:
x² + 7x - 7x - 49 = 0
Combine the same term such as we can either add or subtract +7x to -7x and the result will be equal to 0x.
x² + 0x - 49 = 0
Therefore, the missing number is 0. The answer is 0 which will result to x² +0x - 49.
Answer:
<em><u>22x + 2</u></em>
Step-by-step explanation:
7x + 4 + 12x + 4 + 3x - 6
(*rearrange*)
7x + 12x + 3x + 4 + 4 - 6
= 22x + 2
Answer:
y=20 , x =30
Step-by-step explanation:
x+y=50;
20x+30y=1200
20x+20y=1000, multiplying the top by 20
-20x-30y=-1200, subtracting the second.
-10y=-200
y=20 adult tickets ($600)
x=30 student tickets ($600)
(add up to $1200)
