Which of the following subsets of m3(ℝ) are subspaces of m3(ℝ)? (note: m3(ℝ) is the vector space of all real 3 x 3 matrices) a. the invertible 3×3 matrices b. the 3×3 matrices with all zeros in the second row c. the diagonal 3×3 matrices d. the 3×3 matrices in reduced row-echelon form e. the 3×3 matrices whose entries are all integers f. the symmetric 3×3 matrices

hi friend

here is your answer

there are two angles that are alternate interior angle with angle 9

the angle 15 and angle 7 are alternate interior angle with angle 9.

hope it is for you so mark my answer as a brainliest

hope this .

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
