, 2p+3)x2+(4p−14)x+16p+1=0
has coincident roots.
The sentence "15% of 4x is 20 less than x"
translates to 0.15 • (4x) = x – 20
Solving that…
0.15(4x) = x - 20 multiplipy 0.15•4
0.6x = x - 20 subtract x from both sides
-0.4x = - 20 divide both sides by -0.4
x = 50
A=A trapeze+ A rectangular trapeze
A= (6.5+3.2)*4.5/2 + (1.8+4.5)*4.5/2= (9.7+6.3)*4.5/2=16*4.5/2=8*4.5=36 m^2
