Option 1.
(I don't really have any explanation to add on)
This question is checking to see if you remember what the three angles
of any triangle always add up to. Apparently you don't, or you would not
need to go out looking for somebody who does.
The three angles inside every triangle always add up to 180° .
If two of them add up to 135° , then that leaves
(180° - 135°) = 45° .
for the one remaining angle.
4x^2-9=4(x^2-9/4)=4(x-3/2)(x+3/2) i think that is correct answer.
Answer:
Step-by-step explanation:
(-9/6) / (3/-2) ; reciprocal of -3/2 = - 2/3
so
(-9/6) * (-2/3)
= 18/18 (negative times negative equals positive)
= 1
