D=20in=lV2
l=20/V2=20V2/2=10V2
P=4*l
P=4*10V2
P=40V2
If the face is a square, then (l*l)
If the face is a triangle, then (b*h)(1/2)
If the face is a rectangle, then (l*w)
If the face is a circle, then (r²)(3.14)
You can then add all these faces up to get the total surface area of the prism.
Answer:
B
if f(x-4) then we should put x-4 where the x is spouse to be so;
-2(x-4)-1 =
-2x + 8 - 1 =
-2x + 7
Answer:
113
Step-by-step explanation:
I would round 68 to 70 and 23 to 20. Then I would multiply ; 70*20=1400
