Answer:
It is important because it allows you to calculate the surface area of a trapezoidal prism
Step-by-step explanation:
Start off by combining like terms on the LHS (the terms with x in them).

Replacing this result with what we had before on the LHS, we get

⇒Solve for x (divide both sides

)
⇒Don't forget about reciprocity rules when dividing. This is the same as multiplying both sides by

⇒

⇒

***This is a proper fraction
Volume = 5 cm * 10 cm * 2 cm
volume = 100 cm³
massa = 700 g
Densidade = massa / volume
D = 700/100
D = 7 g / cm³
I have attached the graph. Your axis is x=-4 and the vertex is (-4,-30)
