Which statement is true about every rectangular pyramid? each lateral face has an area less than the area of the base. at least two of the lateral faces are congruent. each lateral face has the same height. at least one of the faces has a whole number base or height hurry

At least two of the lateral faces are congruent. This is the true statement.

Step-by-step explanation:

The correct statement is : At least two of the lateral faces are congruent.

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
