Step-by-step explanation:
if x is games won
then games lost is x+14
total no of games=40
x+x+14=40
2x=40-14
x=13 games won
First do the multiplication inside the parenthesis
(-y+15) + (7.2y-9)
Remove the parenthesis now
-y+15+7.2y-9
Simplify:
6.2y +6
So your final answer is
Answer:
10
Step-by-step explanation:
The hypotenuse of a triangle is the side that is opposite to the right angle, meaning that none of its endpoints form the right angle. In this case, the hypotenuse is LN which is 10.
Answer:
16.23
Step-by-step explanation:
Use cosine to solve.
cos = adjacent / hypotenuse
cos 52 = 10 / x
(x = AB)
(cos 52)(x) = 10
x = 10 / (cos52)
x = 10 / 0.616
x = 16.2338
AB = 16.23
Answer:
Step-by-step explanation:
x² - y² = (x + y)(x-y)
c² - (5b - 3a)² = (c + [5b -3a]) ( c - [5b - 3s] )
= (c + 5b - 3a) (c - 5b + 3s)
