25. Name the property used in each step. Given: 2(x + 3) – 4(x – 4)
= 2x + 6 – 4x + 16
= 2x – 4x + 6 + 16
= x(2 – 4) + 6 + 16
= x(-2) + 6 + 16
= -2x + 6 + 16
= -2x + 22

i) Given, ii) Distributive property, iii) Commutative property, iv) Distributive property, v) Substraction, vi) Law of signs, multiplication, vi) Sum. Result.

Step-by-step explanation:

25) Name the property used in each step:

i) Given.

ii) Distributive property.

iii) Commutative property.

iv) Distributive property.

v) Substraction.

vi) Law of signs, multiplication.

vii) Sum. Result.

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.

brainliest

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
