What is the surface area of this triangular pyramid? A) 29 in
B) 32 in2
C) 35 in?
D) 37 in?

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

there should be an link icon on the bottom of the text box you get. it looks like a paperclip!

wouldn't that be a) 1

4=4x then divide 4 on both sides and you get x=1
