Oh so easy!
The answer is 4!
The question is
WHAT IS 2+2?
It's written in morse code! I used to study it! :)
For #1 the perimeter if the rectangle would be like 4 vertical and 2 horizontal and the area is 4 x 2= 8
<span>for #2 the first a is 24 the second one for a is 27 the first one for b is 24 and the second one is 35</span>
1. d = -9
2. m = -15
Hope this helped! (:
$49.06 x 100 = 4906 cents
4906/200= 24.53 = approx. 25 cents
Step-by-step explanation:
Step 1: From the given equation, taking the Left Hand Side (LHS) of the equation
Step 2: Simplify the LHS to make it equal to the Right Hand Side (RHS)
LHS = sin^4x - cos^4x = (sin²x)² - (cos²x)²
= (sin²x - cos²x)(sin²x + cos²x)
= sin²x - (1 - sin²x) since sin²x + cos²x = 1
= 2 sin²x - 1
= RHS
Hence proved.
