Answer:
5626 to the nearest hundred is = 5,600
10x^4+ 7x^3-12x^2
= x^2(10x^2+ 7x- 12)
= x^2(10x^2 -8x+ 15x -12)
= x^2[ 2x(5x-4)+ 3(5x-4)]
= x^2(5x-4)(2x+3)
x^2(5x-4)(2x+3)= 0
⇒ x= 0
or 5x-4= 0
or 2x+3= 0
⇒ x= 0
or x= 4/5
or x= -3/2
The final answer is x= 0 or x= 4/5 or x= -3/2~
I read this story last year for my 7th grade year. The correct answer is A!
-26x - 5 = x - 56
That should be the equation that is formed.
If you are attempting to find said number (x), then follow these steps:
First, add five to both sides:
-26x = x - 51
Then subtract x from both sides to get the variable on one side of the equation:
-27 x = -51
Now, divide both sides by -27, which will get you the final answer of:
x = -1.9 (rounded up)
Hope this helps!
