The answer is 45.
15% = 0.15, since you move the decimal 2 places
0.15 x 300 = 45.

Step-by-step explanation:
Rank b
27x^2-81x-9x+27 In this case, just in your mind multiply 27 (coefficient of x^2) by the constant value 27(the end value of the quadratic trinomial). Then find factors that give you the value -90 when you add and 729 (27*27) when you multiply.
Factorise the values
27x( x-3)-9(x-3)
Which will give you
(27x-9)(x-3)
Answer:
D. 1.37, -1.37
Step-by-step explanation:
9x² = 17
x² = (17 / 9)
x = ± √(17 / 9)
x = ± (√17) / 3
x = 1.37, - 1.37
B) y=x-4 not sure how to explain it, but because the y intercept is -4, it is almost certain that the last number will ne -4 and since x is equal to 4 y must equal x-4. Might be wrong though ('o')
