Answer:
-8 or -1
Step-by-step explanation:
x*2+9x+8=0
(x+8)(x+1)=0
x+8=0 or x+1=0
x= -8 or x= -1
The solution to the answer is as follows:
<span>x - y = 1...[1],
2x + y = 19...[2], {[1]+[2]}---> 3x = 30,
ie., x = 10. C is correct answer.

I hope my answer has come to your help. God bless and have a nice day ahead!
=(3x^3-y^2)^2 [ open it in (a-b)^2 form]
=(3x^3)^2-2.3x^3.y^2+(y^2)^2
=3^2x^3×2-6x^3y^2+y^2×2
=9x^6-6x^3y^2+y^4. ans
Any expression has many equivalents. For something like this, it is often convenient just to make use of the distributive property.
= (-1/2)*(-3y) +(-1/2)*(10)
= (3/2)y -5
Another equivalent has a common denominator
= (3y -10)/2
Hello!
To convert a fraction to a decimal you have to make the denominator 100
Since the denominator is already 100 we put the numerator behind the decimal point
The answer is 0.68
Hope this helps!
