Select all the expressions that are equivalent to the expression 0.6(-7 - 1.2x).

-4.2 - 1.2x
-4.2 - 0.72x
-0.72x + (-4.2)
-4.2 + 0.72x
-4(0.18x + 1.05)
0.6(-7) - 0.6(-1.2x)
0.6(-7) + 0.6(-1.2x)

-4.2-0.72x or 0.6(-7)+0.6(-1.2x)

Step-by-step explanation:

0.6(-7-1.2x)=-4.2-0.72x

-4.2 - 0.72x (second)

-0.72x + (-4.2) (third)

-4(0.18x + 1.05) (fifth)

0.6(-7) + 0.6(-1.2x) (seventh)

Step-by-step explanation:

okay so 0.6(-7 - 1.2x) = -4.2 - 0.72x or -0.72x - 4.2 or -4.2 + (-0.72x) or -0.72x + (-4.2) they are all the same meaning these are all the simplified answers

so the first one is incorrect because it is -4.2 - 1.2x (simplified)

the second one is correct because it is -4.2 - 0.72x (simplified)

the third one is correct because it is -0.72x - 4.2 (simplified)

the fourth one is incorrect because it is -4.2 + 0.72x (simplified)

the fifth one is correct because it is -0.72x - 4.2 (simplified)

the sixth one is incorrect because it is -4.2 + 0.72x (simplified)

the seventh one is correct because it is -4.2 - 0.72x (simplified)

idk

step-by-step explanation:

i don't know

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
