Answer:
Step-by-step explanation:
perimeter of a square = 4 x length (L)
8x - 10 + 8x - 10 = 4L
rearrange the expression
8x + 8x - 10 - 10 = 4L
16x - 20 = 4L
divide both sides for L to stand alone
(16x - 20)/ 4 = 4L/4
(16x - 20)/4 = L
Since Matrix A is added with Matrix B
then each component must be added to its corresponding component
a11+b11=0
a11=-b11
if
a11*b11=-16
then a11=+4 and b11=-4 or a11=-4 and b11=4
a11 is postive so our answer should be
a11=4 and b11=-4
Answer:
104 hours a year
Step-by-step explanation:
Change 8 2/3 to an improper fraction
(3*8 + 2) /3 = 26/3
Multiply 12 * 26/3 for the 12 months she plays
12 * 26/3 = 104 hours
