Answer:
x = -3 or x = -5
Step-by-step explanation:
Solve for x:
(x + 3) (x + 5) = 0
Split into two equations:
x + 3 = 0 or x + 5 = 0
Subtract 3 from both sides:
x = -3 or x + 5 = 0
Subtract 5 from both sides:
Answer: x = -3 or x = -5
Answer:
FE = 14.4
Step-by-step explanation:
Cos = Adj / Hypo.
So
Cos (F) = FE / DF
Cos (26) = FE / 16
FE = Cos (26) * 16
FE = 0.8988 * 16
FE = 14.4
Answer:
have 6 is large and 4 is medium
Step-by-step explanation:
this is my sloution:
first we can think all 10 packs of cups is large
10*2.40=24 dollars
then we subtract
24-21.60=2.4
after that we subtract large and medium
2.40-1.80=0.6
finally is 2.4/0.6=4
so 4is medium
10-4=6 6 is large
