Answer: 0.14
Step-by-step explanation:
fourteen nundredths = 0.14
X^2 - 10x - 9 = 0
first we will move the constant term to the other side
x^2 - 10x = 9
then, to both sides we will add the number that makes the polynomial on the left a perfect square trinomial. Take half of the coefficient of x, then square it. half of the coefficient of x (-10) is -5, and -5 squared is 25. so:
x^2 - 10x + 25 = 34
factor the perfect square trinomial
(x - 5)^2 = 34
x - 5 = plus or minus sqrt(34)
x = 5 plus or minus sqrt(34)
Answer:
154*3-197 or 265
Step-by-step explanation:
154*3 = 462, 462-197=265.
Answer:
x=2
Step-by-step explanation:
55=5(3x+5)
11=(3x+5)
6=3x
2=x
Answer:
x=9
Step-by-step explanation:
2(x+5)=3x+1
Distribute the 2: 2x+10=3x+1
Subtract 1 from both sides: 2x+9=3x
Subtract 2x from both sides: 9=1x
Divide: x=9
