Step-by-step explanation:
Assume that

hence,

now,

attached below is the complete solution
Answer:
A) 2x³+11x²+8x-16
Step-by-step explanation:
When you multiply s(x) by t(x) you get something like this:

You're starting at 400. Each time you're cutting in half.
So the common ratio is 1/2 which means the equation is

which is in the geometric sequence format. So the answer is choice D
The sum of the angles x and y are 127 degrees.
X + Y = 127
The measure of x is 34 more than half the y.
X = (y/2) + 34
X = (y + 68) / 2
X = 127 - Y
(Y + 68)/2 = 127-Y
254-2Y = Y+68
186 = 3Y
Y = 62
X = 127-62 = 65
The measure of two angles are 62 and 65
Answer:
x=12
