1. Write the following statements as an expression: a. 12 more than a number

b. 15 less than a number

c. Four times a number added to 7

2. Are the following expressions equivalent? Explain.
5(2n - 4) 10n - 4

if answered correctly will give brainiest and 108 points

A. x+12
b. 15-x
c. 4x+7
2. no the following expressions are not correct because in 5(2n-4), it requires the distributive formula so the expression will become 10n - 20 not 10n - 4

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
