What is the surface area of the rectangular prism? show how you got it

4268 square centimeters

Step-by-step explanation:

The formula for the surface area of right rectangular prisms is 2((width*lenght)(height*length)(height*width)).

The length of this triangle is 44 cm, the height is 30 cm, and the width is 11.

2((11*44)(30*44)(30*11))=4268 square centimeters

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
