Answer:
a): A line has a total degree of 180. So just subtract it. 180-92 is
y=88
b): Similar to the previous, a right angle has a total angle of 90. 90-45=45.
y=45.
These are all the ones I can figure out. I hope someone else can get c) and d).
Answer:
5 lbs and 2 ozs
Step-by-step explanation:
16 ounces = 1 lbs.
So just add the 2 ounces to the pounds.
6x^2 - x - 40 =(<span>3x - 8)(2x + 5)
and
</span><span>5 + 2x = 2x + 5
</span><span>
so
</span>(6x^2 - x - 40)<span>÷ (5 + 2x)
= [</span>(3x - 8)(2x + 5)] ÷ (5 + 2x)
= 3x -8
answer
3x - 8
