Well, it’s quite surprising to learn that washing and drying may take up to 80 minutes.
20t^2+9t-20 is the answer
The total sum is 180 because 3 angles = 180
54 + 11s + 7s = 180
-54. -54
18s = 126
S = 7
Answer:
x= 13.5
Step-by-step explanation:
f(x) = 2x + 9
f(x) = 36
Set the 2 equations equal to each other;
2x + 9 = 36
Subtract 9 from both sides;
2x = 27
Divide both sides by 2;
x = 13.5
<em>Check:</em>
f(x) = 2x + 9
f(13.5) = 2(13.5) + 9= 27 + 9 = 36
