To find the answer, you have to do 2/3 divided 4, which equals 2/12, which is the same as 1/6. You get the answer 1/6, because 2/3 divided 4 is the same as 2/3 times 1/4, and if you do the math, you get 2/12, and you simplify it to 1/6.
PLZ MARK AS BRAINLIEST!!! THX!!!
-3x(5x + 1) = -15x^2 - 3x
<span>If all your entries are integers, the determinant is also an integer.
</span>For this problem, 1 0
0 13
For this question, you should just fix 3 values and make the 4th value an unknown and solve it.
I hope my answer helped you somehow.
