-4x^5 + 2x^4 + x^3 + 3x^2 + 9x
Hope this helps.
Area=base*height
A=(x+6)(2x+2)
A=2(x+1)(x+6) technically this is the simplified form, but they may want the expanded form...
A=2x^2+14x+12
the answe would be (0,0) because its the midel witch is also the origin
<span>∠B = 45°
</span><span>∠A = 90°
so
</span>∠C = 45° = ∠B
and
<span>AB = AC = 8
answer
AC = 8 cm</span>
