Answer:
x=2
Step-by-step explanation:
let the unknown number be x
now we are to find x regarding the question as an equation, let's form the equation to solve for x
the interpretation of the question is:
(x² + x)/3 = x
by collecting the like terms:
(x²+ x) = 3x
x² + x = 3x
x² = 3x - x
x² = 2x
x = 2
Answer:
pretty sure its 2
Step-by-step explanation:
ignore the messing hand writing but I think this is why
<h2>explanation: give me brainiest</h2>
Step-by-step explanation:
x^3-10x^2+28x-24=0
This is called the "Additive Identity Property (of Addition)". Any number plus or minus 0 is still that number.
This is reflected in the second equation here.
Answer:6x^3+16x^2-42x-40
Step-by-step explanation:
To expand
(-2x-8)(-3x^2+4x+5)
6x^3-8x^2-10x+24x^2-32x-40
Collect like terms
6x^3-8x^2+24x^2-10x-32x-40
6x^3+16x^2-42x-40
