3/4+(−3/8)+(−1/4)=(−3/8)+3/4+(−1/4) =−3/8+[3/4+(−1/4)]

The sides aren't equal

Step-by-step explanation:

True.

Step-by-step explanation:

3/4+(−3/8)+(−1/4)=(−3/8)+3/4+(−1/4)=−3/8+[3/4+(−1/4)]

= 6/8-3/8-2/8=(-3/8)+6/8-2/8=(-3/8)+[6/8-2/8]

= 6/8-3/8-2/8=(-3/8)+6/8-2/8=(-3/8)+[4/8]

=6/8-3/8-2/8=(-3/8)+6/8-2/8=(-3/8)+[4/8]

= 1/8= 1/8 = 1/8

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

a triangular prism is a 3 dimensional shape composed of triangles and rectangles. it is made from two triangular bases and three rectangular sides.
