Answer:
The number of item should be more than to 100.
Step-by-step explanation:
Cost of x items = C(x) = 10x + 5000
Number of items = x
Average cost = 
Answer:
A
Step-by-step explanation:
( 3x² + 4x + 4)(2x - 4)
(6x³ - 12x² + 8x² - 16x + 8x -16)
(6x³ - 4x² - 8x - 16)
Hope this helps!
5+5= 10
10 time 9b is 90b
10 times -7 is -70
Then 90b-70
Answer:
The length of the missing side is: x = 15
Thus, option A) is the correct option.
Step-by-step explanation:
Let 'x' be the missing sides.
From the given triangle, it is clear that the segment cuts the sides into proportional ratios such 9 : 12 and x : 20 respectively.
Therefore,
9 : 12 = x : 20
9/12 = x/20
cross multiplication
12 × x = 20 × 9
12x = 180
divide both sides by 12
12x/12 = 180/12
x = 15
Therefore, the length of the missing side is: x = 15
Thus, option A) is the correct option.
