Answer: R = (-2,0) S = (-9,0)
Answer:
breadth=16cm and length=32cm
Let breadth be X
According to question,
lengtg=2X
Now,
Perimeter=2(l+b)
or,96=2(2X+X)
or,96=2(3X)
or,96=6X
or,96/6=X
or,X=16cm.
length =32 cm and breadth =16 cm
Answer:
Step-by-step explanation:
Step 1: Subtract 10 from both sides.
2x2+20x−10=10−10
2x2+20x−10=0
For this equation: a=2, b=20, c=-10
2x2+20x+−10=0
Step 2: Use quadratic formula with a=2, b=20, c=-10.
x=
−b±√b2−4ac
2a
x=
−(20)±√(20)2−4(2)(−10)
2(2)
x=
−(20)±√(20)2−4(2)(−10)
2(2)
x=
−20±√480

x=−5+√30 or x=−5−√30
Answer:
x=−5+√30 or x=−5−√30
