Answer:
225 square feet
Step-by-step explanation:
the base of the pyramid would be 76 ft², since 12*6=72. Then you get the surface area of the sides. 2 of the sides would be 48 ft², since (12*8)/2=48. The other 2 sides would be 28.5 ft², since (6*9.5)/2-28.5. Then you just add the surface areas of all the sides; 76+48+48+28.5+28.5 to get 225.
Hope this helps! :)
Answer:
d = 5
Step-by-step explanation:
Isolate d in reverse BEDMAS order. In this equation, so the subtraction part then do the multiplication part.
2d -7 = 3
2d - 7 + 7 = 3 + 7 Add 7 to both sides to cancel it on the left side
2d = 10
2d/2 = 10/2 Divide both sides by 2
d = 5
