Answer:
1638m²
Step-by-step explanation:
42×39= 1628m²
Answer:
cos3x+tan3x=0
⟹cos3x=−tan3x
⟹cos3x=−sin3xcos3x
⟹cos23x=−sin3x
⟹1−sin23x=−sin3x
⟹sin23x−sin3x−1=0
This is a quadratic equation in sin3x.
sin3x=−(−1)±(−1)2−4×1×(−1)−−−−−−−−−−−−−−−−−√2×1
sin3x=1±5–√2
If x takes real values, the upper sign must be rejected.
sin3x=1−5–√2
⟹3x=nπ+(−1)nsin−11−5–√2
⟹x=13[nπ+(−1)nsin−11−5–√2]

Answer:
x= -3/4
Step-by-step explanation:
4(4x+ 6)= 12
16x+24=12
16x=-12
x=-3/4
22.7
is the anwser
because irrational is repeating
I'll give you a pdf so you can see it yourself and the correct answer is -32b - 32b
