(8x^2+2x+8)+(3x^3+7x+4)=
8x^2+2x+8+3x^3+7x+4
3x^3+8x^2+(2+7)x+12=
3x^3+8x^2+9x+12
Answer: Option A. 3x^3+8x^2+9x+12
Answer: The process of combining matrices, vectors, or other quantities under specific rules to obtain their product.
Answer:
The answer is x=20
Step-by-step explanation:
27-7=20
x=20
Xn = ar^(n-1)
n = term to find = 6
a = 1st term = 72
r = common ratio = 0.5
now we sub
x6 = 72 * 0.5^(6-1)
x6 = 72 * 0.5^5
x6 = 72 * 0.03125
x6 = 2.25 <===
