Answer:
23.44
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relation ...
Tan = Opposite/Adjacent
tan(38°) = x/30
x = 30·tan(38°) ≈ 23.4386
x ≈ 23.44
Answer:
(x+3)(x-2)(2x)(x+2)
Step-by-step explanation:
First, start by factoring (x²+x-6).
Find 2 numbers that multiply to -6 and add to get 1. This will be 3 and -2.
So, (x²+x-6) will factor into (x+3)(x-2)
Then, factor (2x²+4x).
You can factor out 2x because both terms can be divided by that.
You will be left with 2x(x+2), which cannot be factored anymore.
Combine all the factors to get (x+3)(x-2)(2x)(x+2).
187/578 is 0.3235 Or you could just write 187/578.
