Hello,
I suppose you want to reduce the expression:
Answer A
3x²-4x²-2x+5x+6+9=-2x²+3x-15
11/4 pounds = 2,75 pounds = 2,75 pounds x 2$ + 2,5 pounds x 1,50$ = 5,50$ + 3,75$ = 9,25 $
Total Cost: 9,25$
Answer:
1.84ft
Step-by-step explanation:
From the figure attached,
AB = Height of the window = 15ft
Let the distance between the base of the housr and the fence 'C' = xft
If the angle of depression = 7°
Then angle of elevation of the top of the fence from the house = 7°
Now from right triangle ABC,
tan7° = x/15
x = tan7°×15
x = 0.1227×15
x = 1.84ft
Therefore, distance of the house from the fence is 1.84ft
