If g(x)=4-2X what is g(x-4)
Anything after the g in the parentheses is what is being substituted for X in the first equation, therefore g(x)=4-2(x-4), we simplify to 4-2x+8-->g(x-4)=12-2x
Find the area of the parallelogram with B=10 and H=5
Area of parallelogram is BH therefore 50 units sq
First we will cross multiply, so we get (x+2)*x=x^2+2x Then we cross multiply 2(4)=8 8=x^2+2x Subtract 8 on both sides x^2+2x-8=0 Factor Find 2 numbers that multiplied=8 but added=2 (x+4)(x-2) x=-4,2
