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:
-6 = x
Step-by-step explanation:
3 sqrt (5x-4) = 3 sqrt (7x+8)
Divide each side by 3
3/3 sqrt (5x-4) = 3/3 sqrt (7x+8)
sqrt (5x-4) = sqrt (7x+8)
Square each side
(sqrt (5x-4))^2 = ( sqrt (7x+8) )^2
5x-4 = 7x+8
Subtract 5x from each side
5x-5x-4 = 7x-5x+8
-4 = 2x+8
Subtract 8 from each side
-4-8 = 2x+8-8
-12 = 2x
Divide by 2
-12/2 = 2x/2
-6 = x
