First, you need to find the area of the rectangle. As you already know, the formula for area is length times width. So, you would need to do 7 times 6, which is 42. Now, the triangle is a little more complicated. the height is about 2 and the base is 6. 6 times 2 is 12, but if you remember the area of a triangle, it's B times H divided by 2, so 12 divided by 2 is 6, so 42 plus 6 is 48. I THINK that is the surface area :)

Answer:
11 / 5
Step-by-step explanation:
2 / 5 + 9 / 5
= ( 2 + 9 ) / 5
= 11 / 5
The answer to this question is choice B. To complete the square, we take the coefficient on the x term, halve it, and then square it. This results in -9/2, and then 81/4. This value of 81/4 is added to both sides, allowing for factorization of the lefthand side of the equation.
