Answer:
D. 12m^3n^5
Step-by-step explanation:
<span>So we want to know the new coordinates for the vertex A'(x,y) if we know that the vertex A is at A(-1,2) and vertex B is at B(1,5) and that the triangle ABC is translated 6 units up and 3 units left. So the method is simply to add units 6 to x and 3 to y of A to get A'. Going left means we need to go to negative x direction and going up means we need to go to positive y direction. So: A'(-1-3,2+6) and that is: A'(-4,8). </span>
Answer:
shaded area = total area - the two triangles areas
total area = 5*9 = 45 cm²
first tri area = 1/2 * h *b
= 0.5 * 5 * 2 = 5 cm²
second tri area = 0.5 * 6 * 5 = 15 cm²
shaded area = 45 - 15 - 5 = 25 cm²
Factor out common factors.
-x³-4x²-5x = -x(x² + 4x + 5)
-x(x² + 4x + 5) is your answer
hope this helps
