A and B are matrices. If A= [1 2] find B given that [4 3]
A²=A+B

9514 1404 393

  B = [[8, 6][12, 14]]

Step-by-step explanation:

Subtract A from both sides to get ...

  A² -A = A+B -A = B

Factor out A, and you have ...

  A(A -I) = B . . . . . where I is the 2×2 identity matrix

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply
