Answer:
x = 40 degrees
Step-by-step explanation:
By corresponding angles, the angle above the 75 degree angle is also 75 degrees. Since angles of a triangle add to 180 degrees, x=180-75-65 = 40 degrees.
If you would like to know if 4x2x2 is the same as 4x4, you can find out using the following step:
2x2 equals to 4, so instead of 2x2 you can write 4.
The result is: 4x2x2 = 4x(2x2) = 4x4, which is the same as 4x4 in the second part of the question.
Answer:
x^2 -81
Step-by-step explanation:
(x+9)(x-9)
FOIL
first x*x = x^2
outer -9x
inner 9x
last -9*9 = -81
Add them together
x^2 -9x+9x -81
Combine like terms
x^2 -81
