Answer:
-6x+3
Step-by-step explanation:
0.76 is what my calculator said
Answer:
we just did this in class a few weeks ago in pretty sure its 3 because that's where the line crosses the y axis but im not 100 percent sure good luck!❤
We can represent the base as z and the height as 2z+6. We are going to use the formula A=1/2*b*h and solve for z
180=1/2*z*(2z+6)
360=2z^2+6z
0=2z^2+6z-360
0=2(z^2+3z-180)
0=(z+15)(z-12)
So z=-15 and 12 but it must be positive so then the base is equal to 12
When we plug this into 2z+6 we get 30 for the height
2(12)+6=30
Hope this helps
