For the parallelogram, if m 2 - 4x-20 and m24 - 3x - 11, find m21. The diagram is

pls dont delete this i need the points

Step-by-step explanation:

T = -0.005x^2 + 0.45x + 125

T = 132 => -0.005x^2 + 0.45x + 125 = 132

=> -0.005x^2  + 0.45x +125 -132 = 0

=> -0.005x^2 + 0.45x - 7 = 0

Discriminant: b^2 - 4ac = (0.45)^2 - 4( - 0.005)(-7) = 0.2025 - 0.14 = 0.0625

Discriminant > 0 => the equation has two real and different solutions.

yes
