Answer
11x-2
Step-by-step explanation:
5x+(2)(3x)+(2)(-1)
=5x+6x+-2
now combine like terms
=5x+6x+-2
=(5x+6x)+(-2)
=11x+-2
hope this helps:)
3x-8 = 8x-33
3x-8x = -33+8
-5x = -25
x = -25/-5
x = 5
The answer is <span>Sum of Cubes.
Since there is sign +, we expect it to be the sum. Among all choices, only the last one includes summation, and that is sum of cubes.
Let's check it out.
Sum of cubes can be expresses as:
a</span>³ + b³ = (a + b)(a² - ab + b²)
Let's see what are cube roots of 125 and 8:
∛125 = ∛5·5·5 = ∛5³ = 5 ⇒ a = 5
∛8 = ∛2·2·2 = ∛2³ = 2 ⇒ b = 2
Now, let's implement that in the equation of sum of cubes:
5³ + 2³ = (5 + 2)(5² - 5·2 + 2²)
125 + 8 = 7 · (25 - 10 + 4)
133 = 7 · 19
133 = 133
Therefore, sum of cubes is the right answer.
Answer:
Misleading
Step-by-step explanation:
tell me if I got it wrong
So i take "one hundred and twenty five " to be one full numer: 125
(my alternative understanding is that 100 is a full integer and only 25 thousands, but I don't think that's what the question meant)
thousands: this means that the number will have a form of
x.xxx
(because the smallest number of this form, 0.001 is one thousandth.
so we fill it in:
0.125
and that's the answer!!
(we fill right to left: so if the number was for exmple 25, we'd have to fill it in with 0:
0.025)
