4x^2+4x-8=0
X^2+x-2=0
(X+2)(x-1)=0
X= -2 or 1
Answer:
2x + 11 = 25
x = 7
Step-by-step explanation:
Let the number be x.
Double of x and add 11 equals 25.
2x + 11 = 25
Solve the equation.
2x + 11 = 25
Subtract 11 on both sides.
2x = 25 - 11
2x = 14
Divide 2 on both sides.
x = 14/2
x = 7
Answer: 11, 7
11 + 7 = 18
11 x 7 = 77
The value of x is 14
<h3>How to solve for x?</h3>
From the question, the lines from the center of the circle to the chords have equal measures of 9 units
This line divides a chord into equal segments, where each segment is 7 units
So, we have:
x = 7 + 7
Evaluate
x = 14
Hence, the value of x is 14
