Step-by-step explanation:
( secA + 1)( sec A - 1)
Using the expansion
( a + b)( a - b) = a² - b²
Expand the expression
We have
sec²A + secA - secA - 1
That's
sec² A - 1
From trigonometric identities
<h3>sec²A - 1 = tan ²A</h3>
So we have the final answer as
<h3>tan²A</h3>
As proven
Hope this helps you
Well first you have to solve for the 1st year so 200*.03, .03 represents the 3%. Which would equal 6 dollars so after the 1st year he would have 200+6=206.
Now you do the second year so do 206*.03, which would equal 6.18 so 206+6.18=212.18
Answer= 212.18
Answer:
No solution
Step-by-step explanation:
get rid of parentheses first by multiplying
5x-3=4x+8+x
combine like terms
5x-3=5x+8
-3=8
That solid figure that you are is a square.
