Question

3) Verify the following:
a) (-21) ×[(-4) + (-6)] = [(-21) (-4)] + [(-21) (-6)]
b) 15 x [6 + (-3)] = [15 x 6] + [15 x (-3)]
c) (-15) [(-8) + (-6)] = [(-15) * (-8)] + [(-15) (-6)]​

Answer 1

Step-by-step explanation:

1. 84 - 6 = 84 + 126

78 = 210

2. 15 * 3 = 90 - 45

45 = 45

3. 120 - 6 = 120 + 90

144 = 210

Answer 2

Answer:

a) -21(-4-6)=((-21)(-4))+((-21)(-6))

=-21(-10)=(84)+(126)

=210=210

a is true

b)15(6+(-3))=(15×6)+(15(-3))

=15(3)=90-45

=45=45

b is true

c)(-15)((-8)+(-6))=((-15)(-8))+((-15)(-6))

=(-15)(-14)=(120)+(90)

=210=210

c is also true

hope this helps you
