She will need 12 seconds because -20•12=-240
The price of the ticket would be 9dollars
Square both sides
9(x + 2) = x + 4
Expand
9x + 18 = x + 4
Subtract x from both sides
9x + 18 - x = 4
Simplify 9x + 18 - x to 8x + 18
8x + 18 = 4
Subtract 18 from both sides
8x = 4 - 18
Simplify 4 - 18 to -14
8x = -14
Divide both sides by 8
x = -14/8
Simplify 14/8 to 7/4
<u>C. x = -7/4</u>
Answer:
x=24cm
y=20,78cm
Step-by-step explanation:
sen(30)=
-> x*sen(30)=12 -> x=
= 24cm
cos(30)=y/x -> cos(30)= y/24 -> y=24*cos(30)= 20,78cm
