Twelve cubes stacked in this figure part a: what is its surface area

36 square units

Step-by-step explanation:

well the surface area is:

let's say that the surface of a cube is 1 squared units

so in the figure we have the faces:

up (blue)

down (not seen)

front (green)

back (not seen)

left (yellow)

right (not seen)

so the are of the blue is 6 and also is the down area

the area of the front is 6 and also is the back area

the area of the left is 6 and also the right area

so we have

square units

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

range =5

step-by-step explanation:

to find the range, we take the largest value and subtract the smallest value.

the largest value is 5

the smallest value is 0

the range is 5-0   =5
