Answer:
D. 36
Step-by-step explanation:
The square of half the x-coefficient must be added. That value is (12/2)² = 36.
_____
You're trying to create a trinomial of the form ...
... (a + b)² = a² +2ab +b²
where a = x, and 2b = 12.
The number you need to add is b² = (2b/2)² = (12/2)² = 36.
Step-by-step explanation:
well she uses half the amount of the flour for the sugar so if its 3 cups of flour, then 1.5 cups of sugar.
Beginning with the function y = sin x, which would have range from -1 to 1 and period of 2pi:
Vertical compression of 1/2 compresses the range from -1/2 to 1/2
Phase shift of pi/2 to the left
Horizontal stretch to a period of 4pi, as the crests are at -4pi, 0, 4pi
Vertical shift of 1 unit up moves the range to 1/2 to 3/2
So the first choice looks like a good answer.
To do this, find the surface area of each two-dimensional shape.
The two triangles have a combined area of 24.
The two rectangles have a combined area of 70.
The center rectangle has an area of 42.
Add them together to get 136 as your surface area.
