Step-by-step explanation:
6x - 3x^2 + 2x^2 -2x = 5x^2 + 15x
4x -x^2 = 5x^2 + 15x
-11x - 6x^2 = 0
-6x^2 - 11x = 0
use the quadratic formula
(-b±√(b²-4ac))/(2a)

Answer:
10
Step-by-step explanation:
Step-by-step explanation:
∑⁴ₙ₌₁ -144 (½)ⁿ⁻¹
This is a finite geometric series with n = 4, a₁ = -144, and r = ½.
S = a₁ (1 − rⁿ) / (1 − r)
S = -144 (1 − (½)⁴) / (1 − ½)
S = -270
If you wanted to find the infinite sum (n = ∞):
S = a₁ / (1 − r)
S = -144 / (1 − ½)
S = -288
<u>Answer:</u>
The expression that represents "the sum of x and 8" is x + 8
<u>Solution:</u>
Given, a sentence “the sum of x and 8”
Now, we have to write an expression that represents the above given line and check the correct option.
So, now, let us take the given expression and convert it into the polynomial form.
Take, “the sum of x and 8" → sum of x and 8 → x + 8.
Here "+" denotes sum or addition.
Hence, expression for “the sum of x and 8” is x + 8 and option c is correct.
