(10x + 4) cm 10 Mary is making rectangular picture frames to the proportions shown.
a) Determine a simplified expression for the outside perimeter of
the frame.
b) Determine the outside perimeter when x = 5 cm.
c) Determine a simplified expression for the area of one picture frane.
d) Decermine the area of one frame when x = 5 cm.
e) Determine a simplified expression for the number of square
centimetres of wood needed to make 20 frames the same size.
Assume chere is no waste.

answer: check all that apply, where the options?

step-by-step explanation:

-60.75

step-by-step explanation:

just add the numbers then put the negative sign on it

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
