The triangle that is formed by AMB is a 45 45 90 triangle, so meaning the legs are equal. so in can be concluded that AD = MD, since M is the midpoint of CD, then CD = 2AD
CD = 2(6) = 12 cm
so the perimeter is of the rectangle ABCD is
P = 2l + 2w
P = 2(6) + 2(12)
P = 12 + 24
P = 26 cm
Answer:
3⋅f(−4)−3⋅g(−2) = −12f+6g
Step-by-step explanation:
Write the problem as a mathematical expression.
3⋅f(−4)−3⋅g(−2)
Move − 4 to the left of f .
3⋅(−4⋅f)−3⋅(g(−2) )
Multiply−4 by 3.
−12f−3⋅(g(−2) )
Move − 2 to the left of g .
−12f−3⋅(−2⋅g)
and lastly Multiply−2 by −3.
−12f+6g
Hope this helps you out.
