Answer:
<h2>A. x = 1</h2>
Step-by-step explanation:

Answer:
x² - 4
Step-by-step explanation:
Step 1: Write expression
(x + 2)(x - 2)
Step 2: FOIL
x² + 2x - 2x - 4
Step 3: Combine like terms
x² - 4
812.30/83 = 9.78674698.....
Nearest tenth means one number under decimal place so...
812.30/83 ~ 9.8
Explanation: The 9.7... rounded up to 9.8 because the number after the tenths place (in this case the number after the 7) is greater or equal to 5.
The diagonals of a rhombus bisect each other at right angles, therefore m∠BEC=90°
9z + 45 = 90
9z = 90 - 45
9z = 45
z = 45/9
z = 5
Minus 1 on both sides
Divide by 3 on both sides
C 5 > 7/3
