Answer:
135x^3 + 3x^2 - 46x + 8.
Step-by-step explanation:
(5x-1)(3x+2)(9x-4)
= (5x - 1)(27x^2 + 18x - 12x - 8)
= (5x - 1)(27x^2 + 6x - 8)
= 5x(27x^2 + 6x - 8) - 1(27x^2 + 6x - 8)
= 135x^3 + 30x^2 - 40x - 27x^2 - 6x + 8
= 135x^3 + 3x^2 - 46x + 8.
Answer: 10
----------------------------------------------
Explanation:
Segment TU must be congruent (equal in length) to segment UV in order for the angle TSV to be bisected by segment SU
Bisected = cut in half
So because TU = UV, we can say,
TU = UV
3x+18 = 4x+8
3x+18-3x = 4x+8-3x
18 = x+8
18-8 = x+8-8
x = 10

Answer:
85,999,999.999 999 909
Step-by-step explanation:
The expression represents the difference of a relatively large number and one that is relatively small. That difference is approximately the value of the large number. The exact value requires 17 digits for its proper expression. Most calculators and spreadsheets cannot display this many digits.
<h3>Standard form</h3>
The numbers in standard form are ...
86,000,000 = 8.6×10^7
0.000000091 = 9.1×10^-8
<h3>Difference</h3>
Their difference is ...
86,000,000 -0.000000091 = 85,999,999.999 999 909
In scientific notation, this is ...
8.599 999 999 999 990 9×10^7
