I’m not quite sure what the question is but i’m guessing you need to simplify, if not lemme know and i’ll try help.

first combine the squared terms which is 1.5z^2+z^2= 2.5z^2

second combine the z terms
6z-3z=3z

then combine the numerical terms
4.5-0.3=4.2

so simplified that equation is
2.5z^2 + 3z + 4.2

Answer:

68°

Step-by-step explanation:

ABD is a right angle and the measure of it is 90°

m<CBD + m<ABC = m<ABD

4x + 52° + 8x - 10 = 90° add like terms

12x + 42° = 90°

12x = 48°

x = 4

m<CBD is 4x + 52° replace x with 4

4×4 + 52 = 68°
