Answer:
19a+27b-54
Step-by-step explanation:
First distribute 7 into the first equation. (4a+3b-6) Multiply each coefficient and the constant by 7.
28a+21b-42
Then do the same for -3 and (3a-2b+4).
-9a+6b-12
Rewrite the equation 28a+21b-42-9a+6b-12.
Combine like terms: 19a+27b-54

Answer:
∠ BCA = 45°, ∠ AWD = 90°
Step-by-step explanation:
All angles are right angles by definition.

∠ BCA = 45°
Diagonals are perpendicular bisectors of each other, so
∠ AWD = 90°
