The answer should be 9 rounded because 2 pi r 56.5 will give u that.
the answer is 2• 137= 274
Answer:
b=-3
Step-by-step explanation:
If the expression simplifies to bx that means the
terms and the constant terms must be cancel out.
Simplify it first.

We know –4 + 4 will cancel out. If we simplify this expression to only an x term, then the
terms should be cancelled. Therefore, we say that 4ax^2 – x^2 = 0.

If we put a = ¼, then we can find the value of b:


if the expression is equivalent to bx
Therefore, b = –3.
Answer:
53
Step-by-step explanation:
Sol'n
Let the remaining angle of a triangle be x.
x+71+56=180 (Sum of angles of a triangle is 180°)
or, x+127=180
or, x=180-127
.:, x=53°
.:, The measure of third angle is 53°
