Answer:
7
Step-by-step explanation:
because when you divide with the coeficient it sums out to be 7
Reduce the number of terms in the expression by operating on like terms
for example
Simplify
x^2 - 3x + 4 + x^2 + 6x - 6
the like terms are the x^2 and x^2 , -3x and 6x and 4 and -6
so we have
x^2 + x^2 - 3x + 6x + 4 - 6
= 2x^2 + 3x - 2
This is the simplified form of the original expression

Answer: 45
Step-by-step explanation:
The total degrees in a circle is 360.
The perpendicular angle that you see is 90 degrees, added to angles of x and 3x, you get the total degrees.
so 90 + x + 3x = 90 + 4x = total
90 + 4x = 360
4x = 180
x = 45 degrees
