-2 is the answer! Remove the parentheses then move the terms. After that, collect the terms and calculate. Lastly, divide both sides.
13.6 if you meant .4% of 34 because you multiply them. move the decimal point and solve it
secA=√2
secA=sec45
A=45°
3cos²45+5tan²45/ 4tan²A-sin²45
= 3(1/√3)²+5(1)² / 4(1)²-(1/√2)²
=3/2+5/4-1/2
=13/7
$165 x 48 = $7920 which is what he has to pay in total for 48 months
$7920 + $299 = $8219
therefore, the total he pays for his car is $8219 :)
