Answer:
(x / 149) = .77
.77 * 149 = x
x = 114.73
Step-by-step explanation:
3mm²
Use the triangle area formula 1/2×base×height
18
side 1=5x^2+103x+40
side2=5x^3-43+100
side 3=A {let}
we have
perimeter of triangle=side 1+ side2 +side3
5x^4+5x^3+5x^2+50x+100=5x^2+103x+40+5x^3-
43+100+A
A=5x⁴+5x³+5x²+50x+100-5x³-5x²-103x-97
A=5x⁴-53x+3 is your answer
$250 - (25) (250)
