Answer:
-21x^2+50x-24
Step-by-step explanation:
3x((5)(2)-7x+2)-2((5)(2)-7x+2)
30x-21x^2+6x-20+14x-4
50x-21x^2-24
-21x^2+50x-24
Answer:
Step-by-step explanation:
1) 6 tan2x − 6 tan2x sin2x
=
2) 
3) 
4) x=6cos t
So cost =x/6

so -3sint
5)
Please enclose fractions such as 8/7 inside parentheses:
<span>(8/7)x^3+x^4+6x+1
Next, arrange these four terms in order of power of x:
</span>x^4 + (8/7)x^3+ 6x+1 This is the standard form you wanted.
The perimeters of two opposite triangular faces includes all 4 slant edges and 2 of 4 base edges. The other two base edges are half the base perimeter, so the total length of all edges is
.. 2*(27.5 cm) +(1/2)*(30 cm) = 70 cm
Start (90,100). End (10,0). Waterfall (70,50). The X point is first Y is second. Hope this helps :)
