What do you need help clarifying? Did you want to go over the questions you missed? (:
How you find the area of a triangle is base × height ÷ 2. So the equation would be 6×3=18 18÷2=9, so the answer is 9. Hope this helped!
Find out how old her dad was when Cindy was born by subtracting 2 from 28. Her dad was 26 when she was born. If Cindy is 18 then her dad is 26 years older than that. 18+26=dads age. Dads age is 44.
I graphed the function.
Remember, f(x)= y.
y= -2x^2-16x-34
The vertex was at point (-4,-2)
I hope this helps!
