I'm pretty sure this is the answer:
(10)sin(40°) = AC
It's <em>sin </em>becasue it <em>needs </em>the opposite side of 40° and <em>has </em>the hypotenuse.
So 1st make it equal to zero
x^2+4x-12
(x+6)(x-2)
so
x=-6 or 2 is the correct answer
For the square root of a negative number, you would have to get into imaginary numbers. If you haven't learned about it yet, then the answer would be no real solutions. But if you have, here's how to solve it:
First, identify that 9 x 3 = 27. To after taking the square root, you will get 3√3 (Since the square root of 9 is 3 and there's no square root of 3, so leave it in the √)
However, since it is a negative number, you will have to include the letter i in the answer. i represents the imaginary part of it since you can't have a negative number in the square root.
So your answer will look like 3i√3.
You probably mean either
or
Write 8 = 2³, so that in the first interpretation,
and in the second,
Then in the first interpretation, we have
Otherwise, the second interpretation gives
Answer:
26,068
Step-by-step explanation:
(-343) x (-12) + (-343) x (-88)
= -4116 + 30,184
= 26,068
