Using the shortcut for binomial expansion, which still took 45 minutes, I got 23-26. The coefficient on the x^6 term is 34,020; the coefficient on the x^4 term is -495; on the x^7 term it's 1800; on the x^3 term it's 337,920. I'm pooped. The rest is factorial notation, kinda the same thing, but...
Answer:
Step-by-step explanation:
Cross multiplying
5z =14*24
5z = 336
Divide by 5
z = 336/5
Or mixed fraction z= 67(1/5)
Decimal z= 67.2
Answer:
B=112
Step-by-step explanation:
Angle B is on the same line as angle A(68). They would need to combine for a total of 180 degrees. So 68-180=112
That is basically splitting the sentence so that it’s easier for you to solve it. It’s basically the same thing
