The wording of the question kinda doesn't make sense in some parts, but I'll try anyway. 1 plus 4 is 5, and since BC is 5, x is 1 for BC. -3 plus 14 is 11, so x is -3 for AB.
Answer:
2. 4
Step-by-step explanation:
use the formula A=ab/2
a-leg 1
b-leg 2 (base)
since it is a right triangle the height would be 2 cm and the base would be the leg (4 cm)
plus into the equation- A= 2(4)/2
8/2=4
If I could get more context then that would help. Because an exponent being an odd number doesn’t do anything, so it could be either a negative or a positive
