130 you multiply the left side by 13 to get the right side.
Answer:
32, 45
Step-by-step explanation:
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:
A.
Step-by-step explanation:
Answer:
24
Step-by-step explanation:
In a deck of 52 cards, there are 4 kings and 4 queens
Selection of 3 kings out of 4 = 4 C 3 = 4
Selection of 2 queens out of 4 = 6
So, total number of selections = 4 x 6 = 24
