Answer:
3x + y
Step-by-step explanation:
combine like terms
-3x + 6x = 3x
2y - y = y
Final Answer: 3x + y
Find the area of the triangle, then multiply by the depth of the prism:
Area of a triangle = 1/2 x base x height = 1/2 x 15 x 3 = 22.5 square inches.
Volume = 22.5 x 13 = 292.5 cubic inches.
Answer:
108
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles
<1 + <2 = <4
33 + 75 = <4
108 = <4
9514 1404 393
Answer:
A
Step-by-step explanation:
The axis of symmetry of quadratic ax²+bx+c is x=-b/(2a). For the given equation, the axis of symmetry is ...
x = -4/(2(3/2)) = -4/3
The only graph with its vertex at x=-4/3 is graph A.

<em>Additional comment</em>
You can also make the correct choice by evaluating the equation at a couple of different values of x. Convenient ones are x= -1, or 0, or +1. The value at x=0 is the y-intercept, (0, -2), which seems to be a point on all of the graphs. The value at x=1 is 3/2+4-2 = 3.5, which looks like it is only seen on graph A.
