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.
Let
x-----> the measure of the angle formed by the wooden fence and grass
we know that
in a right triangle
tan x=opposite side angle x/adjacent side angle x
opposite side angle x=13 ft
adjacent side angle x=21 ft
so
tan x=13/21x=arc tan (13/21)-----> x=31.76°------> x=32°
the answer is
32 degrees
Answer:
(2x/3) - 4
Step-by-step explanation:
"twice a number" ---> 2x
"quotient of twice a number and 3" ---> 2x/3
"4 less than" --> (2x/3) - 4
Could also be written as (2/3)x - 4
