Hello there.
What is 125x9+64y12 written as a sum of cubes
125x9+64y12 written as a sum of cubes would be:
(5x3)3 + (4y4)3
First of all you have to use pemdas perentheses, exponents, multiplication, division, addition and subtraction. so 8 multiplied to nine and 9 multiplied to 12 and then add them together.
The answer is quadratic.
A quadratic equation takes this form:
<em>ax^2+ bx + c</em>
The "a,""b,"and "c" represent numerical coefficients.
This is how your equation looks:
3x + x^2 + 4
Now it is standard that we organize the polynomial in descending order so it will look like this:
x^ 2 + 3x + 4
(commutative property of addition says that the arrangement will not affect the result)
It matches the quadratic polynomial form.
<em>* You might be thinking, x to the second power has no number next to it though, well actually it does. The numerical coefficient of x to the power of two in this case is actually 1. It's just that in math, it is not necessary to put the one anymore. It is already assumed. </em>
<h3>Solution:</h3>
- Here, the whole line segment is AD.
- So, AB + BC + CD = AD.
- Given, AD = 20
- BC = 2
- AB = 12x
- CD = x + 12
- Therefore,
AB + BC + CD = AD
or, 12x + 2 + x + 12 = 20
or, 13x + 14 = 20
or, 13x = 20-14
or, 13x = 6
or, x = 6/13
<h3>Answer:</h3>
x = 6/13

Answer:
Just multiply:
= 0.06×0.021
= 1.26
is this the right answer I don't even know my answer
