(28 : 100) *6 = 1.68 (tax)
28 + 1.68 = 29.68 (total cost)
3^6
or
729 because 3 time 3 times 3 times 3 time 3 times 3 is 729
Answer:
x =7
Step-by-step explanation:
Solve for x:
5 x - 10 + 65 = 90
Add like terms. 65 - 10 = 55:
5 x + 55 = 90
Subtract 55 from both sides:
5 x + (55 - 55) = 90 - 55
55 - 55 = 0:
5 x = 90 - 55
90 - 55 = 35:
5 x = 35
Divide both sides of 5 x = 35 by 5:
(5 x)/5 = 35/5
5/5 = 1:
x = 35/5
The gcd of 35 and 5 is 5, so 35/5 = (5×7)/(5×1) = 5/5×7 = 7:
Answer: x = 7
If you observe the graph, the graph is touching the x-axis at the point x=-1 and is turning away.
This means, the graph as an even multiplicity at x=-1. So the two roots of the given polynomial are x = -1 and x = -1. Thus, the two factors of the polynomial are (x+1) and (x+1)
Product of the factors is equal to the polynomial. So the given polynomial will be (x+1)(x+1).
Therefore, the answer to this question is option C
