Find all possible solutions for x and y such that △ABC is congruent to △DEF. △ABC: sides of length 7, x − y, and x + y

△DEF: sides of length 7, 17, and 19

Find all possible solutions for x and y such that △ABC is congruent to △DEF.

△ABC: sides of length 7, x − y, and x + y

△DEF: sides of length 7, 17, and 19



△ABC ≅ △DEF when x is [ ] and y is either [ ] or [ ]

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

2.   never

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
