20(-1) - (-4) (-5)
2 [-12 + (-3 - 3)]
Plz help I don’t understand

1. 20(-1) - (-4) (-5)= -40

2.[-12 + (-3 - 3)]= -18

Step-by-step explanation:

20(-1) - (-4) (-5)

=(20 * -1) - (-4 * -5)    

(When 2 numbers are written next to each other in   brackets without any sign in between them, it means multiplication)

=(-20) - (20)

= -20 -20

= -40

[-12 + (-3 - 3)]

=[-12+(-6)]

=[-12-6]

= -18

the answer is b

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap
