Answer:
y = ax2 + bx + c
Step-by-step explanation:
1) Standard form: y = ax2 + bx + c where the a,b, and c are just numbers.
2) Factored form: y = (ax + c)(bx + d) again the a,b,c, and d are just numbers.
3) Vertex form: y = a(x + b)2 + c again the a, b, and c are just numbers.
The area of a triangle is base x height x (1/2)
Plug in the values that are given.
Area = 10 x 12 x (1/2)
Area = 120 x (1/2)
Area = 60 in²
Hope this helps :)
