10! If you use the trapezoid area formula and plug in the known values, just solve for h(height)
3x^2 -6x + 6 :) hope this is alright
X=5, if that’s what you’re solving for
M(N+2)+3N+6
M*(n+2)+3(n+2)
Answer
(n+2)*(m+3)
0.10d + 0.25q = 3.55
q = d + 3
0.10d + 0.25(d + 3) = 3.55
0.10d + 0.25d + 0.75 = 3.55
0.10d + 0.25d = 3.55 - 0.75
0.35d = 2.80
d = 2.80/0.35
d = 8.....8 dimes
q = d + 3
q = 8 + 3
q = 11 <=== 11 quarters
