Answer:correct answers
Step-by-step explanation:
To solve this we need to use this formula:
a(b+c)=ab+ac
5(7+3x)-12=35+15x-12=15x+23
Answer:
Marked Price =MP=550 Marked Price =MP=550
Selling Price=SP=550-10%=550-55=495Selling Price=SP=550-10%=550-55=495
The profit earned is , SP−Profit=CP(CostPrice)The profit earned is , SP−Profit=CP(CostPrice)
CP=495−75=420CP=495−75=420
The difference of MP and CP is 550−420=130The difference of MP and CP is 550−420=130
The percentage of difference w.r.t CP is The percentage of difference w.r.t CP is
130420×100=30.95%

plz make me as a brainliest
YES! quite easily.
I hope you can see the two pairs of corresponding angles between the parallel lines. they'll be equal
and then there's a pair of vertically opposite angle at centre.
that means all pairs of corresponding angles are equal, thus, triangles are similar by AAA
