Create a matrix that is equal to F+G. The first matrix below is named F and the second matrix below is named G. Name the new matrix with the answers in it H. Then answer the following question: what is the element address H31. Round your answer to tenths place

  see attached

  H31 = -0.2

Step-by-step explanation:

The matrix sum H is the element-by-element sum of corresponding elements of F and G. For example, H31 = F31 +G31 = -4.7 +4.5 = -0.2.

For repetitive calculations using the same formula, it is convenient to do them using a spreadsheet.

the answer is ! ?

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
