Millie makes a placement with a triangular pattern each triangle has a base of 5 inches in height of 4 inches Millie souls together a total of 42 triangles you triangle has an area of the total area of the placemat is

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.

total of apples - take away four

6-4 = 2

answer is 2 apples

they would have to work 32 hours.

i think the answer would be c
