Please double check to ensure that y ou have copied the original problem correctly. <span>x^2-x-12 x 2 − x − 12. What do you mean by -12 x 2? Perhaps you meant -12x^2?

Just suppose that you meant -12x^2. Then your expression becomes

</span><span>x^2-x-12x^2 − x − 12 and this simplifies to -11x^2-2x -12. Not easy to factor!

So, once again, please ensure that you have copied down this problem exactly as it was given in your assignment.</span>

A ship is anchored off a long straight shoreline that runs north and south. From two observation points 16 miles apart on shore,

ELEN [110]

D - the shortest distance from the ship to the shore.
d / ( 17 - x ) = tan 32° = 0.62487
d / x = tan 53° = 1.32704
d = 0.62487 ( 17 - x )
d = 1.32704 x
0.62487 ( 17 - x ) = 1.32704 x
10.62279 - 0.62487 x = 1.32704 x
x = 10.62279 : 1.95191
x = 5.44226 miles
d = 5.44226 · 1.32704
Answer:
d = 7.222 miles

How do i do this problem 0.25(x+4)-3=28

KiRa [710]

Distribute the .25 to get .25x + 1 - 3 = 28

Then simplify to get .25x - 2 = 28

Move the two to the right to get .25x = 30

Then divide to leave x: 30 / .25 = 120

X = 120
