What are the solutions to the quadratic equation 4x2 + 28x = 0?x = 4 and x = −7
x = 4 and x = 7
x = 0 and x = −7
x = 0 and x = 7
Answers
First step: take out the GCF
4x(x + 7) = 0
2nd step: equal each expression to 0
4x = 0
(x + 7) = 0
3rd: solve
4x= 0
x = 0
x + 7 = 0
x= -7
So the answer is x= 0 and x= -7
Answer:
x=0
x= -7

x = 100%
20x = 14 . 100
20x = 1400
x = 1400
20
x = 70
S = 20% of 70 is 14.
20 percent of 70 number is 14.
Here we have to find,
The number of which 20 percent is 14
Le the number = x
Now divide 20 by 100
20% = 20/100
= 0.20
Now multiply 0.20 with x we get,
⇒ 0.20x
Now equate it tp 14 we get,
⇒ 0.20x = 14
⇒ x = 14/0.20
= 70
Hence,
The number is 70.
