Step-by-step explanation:
This shape is a quadrilateral.
All angles in a quadrilateral add up to 360 degrees.
There is two right angles- right angles measure 90 degrees.
90 + 90 = 180
You are given the the angle 56 so add that to 180.
56 + 180 = 236
To find x, we subtract 236 from 360.
360 - 236 = 124
x = 124 degrees
It’s A number 2....................../
Step-by-step explanation:
81x⁴ - 16y⁴
(9x²)² - (4y²)²
(9x² + 4y²)(9x² - 4y²)
(9x² + 4y²)(3x + 2y)(3x - 2y)
Answer:
The first option is correct.
Step-by-step explanation:
how do we multiply x - 9 by something? we put it in brackets
(x - 9) × (-3) = 51
that can be written like this
(x - 9)(-3) - 51
