Douglas said he can find 240÷10 by taking the 0 off 240 to get 24. Douglas finds 59.20÷10 using the same method and gets 59.2. U

Answer:

Douglas is incorrect

Step-by-step explanation:

We can remove a zero from a number that has a zero on the right of the decimal place if that zero is the last number before the decimal place. This is true for 240 divided by 10 because the zeros cancel out:

=240/10=24

In 59.20 this is not true. Dividing a number with a decimal place requires the decimal place to move and not cancel out the zero after the decimal place. Therefore:

=59.20/10=5.92

How do you solve this problem: 5(x3)-(-20)
Nimfa-mama [501]
First step: multiply the 5(x3) and it will give you x15 or most commonly written as 15x. you should now have 15x-(-20).

Second step: since you cannot subtract -20 from 15x because it has a variable, the final answer is just 15x-(-20), or 15x+20.

X^2 + 32x + 256 = 1<br>please show steps​
Elena L [17]

\boxed{x_{1}=-15} \\ \\ \boxed{x_{2}=-17}

<h2>Explanation:</h2>

In this case, we have the following equation:

x^2+32x+256=1

But we can write this equation as:

x^2+32x+256=1 \\ \\ Subtract \ -1 \ from\ both \ sides: \\ \\ x^2+32x+256-1=1-1 \\ \\ x^2+32x+255=0

So this final result is a quadratic equation written in Standard Form (ax^2+bx+c=0). We need to find the solutions to this equations, so let's use quadratic formula:

x=\frac{-b \pm \sqrt{b^2-4ac}}{2a} \\ \\ a=1 \\ b=32 \\ c=255 \\ \\ \\ x=\frac{-32 \pm \sqrt{(32)^2-4(1)(255)}}{2(1)} \\ \\ x=\frac{-32 \pm \sqrt{1024-1020}}{2} \\ \\ x=\frac{-32 \pm \sqrt{4}}{2} \\ \\ x=\frac{-32 \pm 2}{2} \\ \\ Finally, \ two \ solutions: \\ \\ \boxed{x_{1}=-15} \\ \\ \boxed{x_{2}=-17}
