Answer:
17w+35
Step-by-step explanation:
(2+2w)⋅4+9(w+3)
Distribute the 4 and the 9
2*4 + 2w*4 +9*w+9*3
8+8w +9w +27
Combine like terms
8w+9w +8+27
17w +35
<span>Best Answer: 1) Q is positive therefore the process is endothermic. .769kj+-.810kj=-.041kj
2) Heat is released meaning it is exothermic. -66.9kj+45=-21.9kj
3) 7.29kj. Endothermic.</span>
Answer: X does not intercept (none)
Y=(0,5)
Step-by-step explanation:
Answer:
cos theta = adj / hyp is positive (+/+)
Step-by-step explanation:
In this open interval, the hypotenuse (radius) is always positive, whereas the adjacent side is positive and the opposite side negative.
in this interval:
sin theta = opp / hyp is neg (-/+)
cos theta = adj / hyp is positive (+/+)
tan theta = opp / adj = (-/+) : negative
