Answer:

AC = 24

DE = 18

Step-by-step explanation:

Assume that the given figure is a parallelogram. One of the properties of a parallelogram is that the diagonals bisect. This means that the following statements are true:

2 ( CE ) = AC

Substitute,

2 ( 12) = AC

24 = AC

(BD) / 2 = DE

Substitute,

(36)/2 = DE

18 = DE

Need help nadding and subtracting functions

SCORPION-xisa [38]

Answer:

2x² + $\frac{3}{2}$ x - 5

Step-by-step explanation:

(f + g)(x) = f(x) + g(x), thus

f(x) + g(x)

= $\frac{x}{2}$ - 2 + 2x² + x - 3 ← collect like terms

= 2x² + $\frac{3}{2}$ x - 5
