Answer:

2*3 matrix

Step-by-step explanation:

well multiplying matrices is just multiplying first row of first matrix * first column of second matrix and so on, so 2*3 matrix times 2*1 matrix equals 2*3 matrix.

Can you help me find x
kifflom [539]
X = 30

hope that  helps

180 - 108 = 72

180 - 72 -43 = 65

triangle on the left 
Angles = 43,65,72

triangle on the right

180 - 65 = 115

180 - 115 - 35 = 30
so angles of triangle on the right = 30, 35, 115

x = 30 (vertical angles with the other angle of triangle on the right)

Grace [21]

Answer:

Step-by-step explanation:

Rearrange the terms and take out a common factor of 4

4(8x^2 + 2x + 1)

I think this is as far down as you want to take it. It gives an imaginary root which you may not be familiar with.
