<span>(3)(8) = (8)(3)
answer is </span><span>A. Commutative</span>
We have to factor becasue
area=legnth times width
area=4x^2+28x+49
area=(2x+7)(2x+7)
area=(2x+7)^2
legnth =width
we arent' given area so we can't solve
but, , since it is a squaer room, legnth=width so √area=legnth=width
324 is the answer to your promblem welcome
These are vertical angles so they are equal so
6a + 11 = 2a + 83
now solve for a
