<span>an expression that is equivalent to three over four (5z+ 16).</span>
Step-by-step explanation:
f(g(x))=(3x+1)^2 +2(3x+1) -4
=9x^2 +6x +1 +6x +2 -4
=9x^2 +12x +(-1)
The variable x represents the base.
x+(x-52)+(x+56)=166
3x+4=166
3x=162
x=54
Final answer: 54 cm
bearing in mind that the slope goes by several names
• average rate of change
• rate of change
• deltaY over deltaX
• rise over run
• gradient
• constant of proportionality
