7. The variable expression 2p + 3 represents the word phrase [A] half Sam's age times three. [C] twice Sam's age times three. [B] three times Sam's age. [D] three more than Sam's age doubled.

D. three more than Sam's age doubled

D) three more than his age doubled

Step-by-step explanation:

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

show us the graphs dude
