You would have to do this (1.25X3)+(0.45X2)=x then x=4.65, because 3X1.25=3.75 and 2X0.45=90 and 3.75+90=4.65

Step-by-step explanation:
length of the third side = Perimeter - ( sum of the length of other two sides}
=15x - 6 - ( 7x-4+3x+2)
=15x-6 -(10x-2)
=15x - 6 - 10x + 2
= 5x - 4
Answer:
(2,4)
Step-by-step explanation:
y = 4x - 4
2x + 3(4x - 4) = 16
2x + 12x - 12 = 16
14x = 28
x = 28/14
x = 2
y = 4(2) - 4
y = 8 - 4
y = 4
