How would i solve this and what is the answer for this question? ?

∆DFE

Step-by-step explanation: congruent means in agreement and harmony. When you look very closely at the diagram, you will notice a similarity between them. For example Line AB is equivalent to line DF and so on.

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 -
