Answer:
L=W+X X=2 feet, W=width, L=length
if you were to solve it then you would get L=8
Step-by-step explanation:
(a). The element a₂₁ is the number of boys enrolled in Lacrosse.
(b). The address is a₁₂.
(c). [196 174]
[136 169]
[214 242]
(d). The matrix represents the number of boys and girls from towns A and B enrolled in different sports classes.
(e). 1.125 A = [108 90 ]
[72 99 ]
[117 135]<span />
Answer:
f your number is x, then the difference between that number and 8 would be x-8. Twice that is 2(x-8)
Three times the sum of the number and 3 would be 3(x+3). So, you get the equation:
2(x-8)=3(x+3)
2x-16=3x+9
x=-25
The upper comment is correct
