Муну ушундан көбөйтүшүңүз керек, андан кийин эмне болуп жатканын түшүнүш үчүн бөлүң!үз. балким, бул жерде, бул татаал нерсе. сиз тегерек болушуңуз керек, балким, ушул сыяктуу нерсени билип алыңыз?
Doa. :)
First, distrbute -3 to both -4y and 3
-3(-4y) = 12y -> note that two negatives multiplied = one positive answer
-3(3) = -9 -> note that one negative and one positive = one negative answer
12y - 9 + 7y -> combine like terms
12y + 7y - 9
19y - 9 -> answer
Your answer is 19y - 9
hope this helps

Answer:
x = 3 and y = 2
x = 1.25 and y = 1.75
Step-by-step explanation:
Part 1:
See the diagram first.
If the two arrow lines are parallel then, the two triangles are similar.
So, the corresponding sides of the triangles are proportional.
So,
Hence, x = 3 and y = 2 (Answer)
Part 2:
See the diagram first.
If the two arrow lines are parallel then, the two triangles are similar.
So, the corresponding sides of the triangles are proportional.
So,
⇒
⇒ x = 1.25
Again,
⇒ y = 1.75
Hence, x = 1.25 and y = 1.75 (Answer)
