Answer:

D. no solution

Step-by-step explanation:

h-z=3(1)

h=3+z(minus z from both side)

put in the second equation

-3h,+3z=6(2)

-3(3+z)+3z=6

-9-3z+3z=6

-9=6( not true)

so the equation doesn't have a solution.

Answer is angAOC=90

Is A O B is in one line so
2a+62+54-a+5a-20=180
6a=180-62+20-54=84
a=14
angAOC= 2a+62=90
angCOD=54-a=40
angDOB=5a-20=50
SO angAOC is the biggest

Subtract the matrices. What number fills in ?
lesya [120]

The missing number for the subtraction of matrices is 4.

<h3>How to subtract the matrices?</h3>

The subtraction of two matrices of the same size is really direct. You just need to subtract the elements that are in the same position, then:

A = \left[\begin{array}{ccc}a_{11}&a_{12}\\a_{21}&a_{22}\end{array}\right] \\\\B =  \left[\begin{array}{ccc}b_{11}&b_{12}\\b_{21}&b_{22}\end{array}\right]\\\\A - B = \left[\begin{array}{ccc}a_{11} - b_{11}&a_{12}-b_{12}\\a_{21} - b_{21}&a_{22}-b_{22}\end{array}\right]

Then the missing therm will just be equal to the difference between the last two elements of each matrix:

-2 - (-6) = -2 + 6 = 4

The missing number is 4.
