Step-by-step explanation:
hello :
√(5/4)= √5/ √4 =√5/2 = (1/2)√5
3+√5/4−√5 = 3+(1/2)√5 so : a=3 and b= 1/2
Answer:
-1
Step-by-step explanation:
First we combine like terms, so y2 - 5y = - 3y
Now we get - 3y = 3
Then we divide both sides by - 3
Now we get y =-1

Answer:
QR=RS=QS=29
Step-by-step explanation:
Given QRS is an equilateral triangle, thus all the three sides of the given triangle will be equal.
Also, from the given statement, we have
QR=2x-7, RS=5x-61 and QS=11+X
Now, As all the sides of the triangle are equal, therefore
QR=RS=QS
⇒QR=RS
⇒2x-7=5x-61
⇒-7+61=5x-2x
⇒54=3x
⇒x=18
Thus, the measure of QR=2(18)-7=29,RS=5(18)-61=29 and QS=11+18=29.
