The answer is infinitely many solutions because 0 = 0.
If you don't seem to see where I got 0 = 0, look at the equation,
4b – 4b = 0
first lets do the math on the left side.
4b - 4b is equal to 0.
so lets put 0 on the left side, now lets look at the equation all together,
0 = 0,
and this means that it has infinitely many solutions.
The reason why it is not no solution because no solution means when there are no answers to the equation. For example, the solution is not true, such as the equation 24 ≠ 29. This is a no solution equation. One solution can be 4x = 20, as x = 5, concluding it being one solutions.
Answer:
Rounded to the nearest tenth the solutions to the equation are:
x = -1.7 and x = -6.3
Step-by-step explanation:
Since this is a quadratic equation of the form:

Use the quadratic formula, which tells you that the solutions would be given by:

So in our case, the quadratic formula gives:

which gives us two real solutions:
x = - 1.654792
x = -6.345207
Which rounded to the nearest tenth give:
x = -1.7 and x = -6.3
-1/5 + (-3/4)
= -1/5 - 3/4
= -4/20 - 15/20
= -19/20
Answer:
x²+3x+1

Answer:

Step-by-step explanation:
Start by setting the width = x.
Length is equal to x+20.
We know the cost of the land was $12 per square foot (area) and the cost of the fence around the perimeter is equal to $8 per foot. This gives us two equations we need to work with.
$12(x*(x+20)) + $8((2*x)+(2*(x+20))) = 10560. It looks a little difficult to read but as we distribute the cost throughout the equations, we see it start to take shape.
12(x^2+20x) + 8(2x+2x+40) = 10560
12x^2+240x+16x+16x+320 = 10560
12x^2+272x+320=10560
The roots of our equation here are x=20, and x = -128/3
Since we know that area is not negative, our answer is x=20.
Check the work: 12(20)^2 + 272(20) +320 = 10560
