Answer:
4,784ft^2
Step-by-step explanation:
Well in this case we will just use the square and triangle area formulas instead of the pyramid surface area formula.
So if the base is a square then the area is 32*32 which is 1,024.
Now for the trangle, the area of a triangle b*h/2.
So b*h is 47*32 which is 1,504.
So 1,504/2 is 752.
So 752 is the area of 1 triangle and we have 4 so 5*752 is 3,760.
So 3,760 + 1,024 is 4,784.
So the total SA if the pyramid is 4,784ft^3.
Answer:
Each get 5
Step-by-step explanation:
solve this answer by using substitution. set the first equation to x=-y+4 then substitute -y+4 for x in the second equation.
2(-y+4) + 3y=0
-2y+8 + 3y=0
y+8=0
y=-8
now use -8 and solve for x
x+(-8)=4
x=12
