Answer:
15
Step-by-step explanation:
Let's call the mystery number x.
Hope this helps!
You multiply the binomial by the whole trinomial.
So 5x^2 (5x^3 - 6x^2 - 5) and then -2x (5x^3 - 6x^2 - 5)
then solve so it is:
25x^5 - 30x^4 - 25x^2 - 10x^4 + 12x^3 + 10x.
Then you simplify to:
25x^5 - 40x^4 + 12x^3 - 25x^2 + 10x

Answer:
x = -2
y = 1
Step-by-step explanation:
x−2y=6
<em>Multiply both sides by 2</em>
x-4y=12
<em>Subtract x from both sides</em>
-4y=12-x
2x−4y=10
<em>Subtract 2x from both sides</em>
-4y=10-2x
Put the 2 equations together:
12-x=10-2x
<em>Add x to both sides</em>
12=10-x
<em>Subtract 10 from both sides</em>
2= -x
<em>Multiply both sides by -1</em>
x= -2
x−2y=6
<em>Multiply both sides by 2</em>
2x-2y=12
<em>Add 2y to both sides</em>
2x=12+2y
2x−4y=10
<em>Add 4y to both sides</em>
2x=10+4y
x−2y=6
<em>Multiply both sides by 2</em>
2x-2y=12
<em>Add 2y to both sides</em>
2x=12+2y
2x−4y=10
<em>Add 4y to both sides</em>
2x=10+4y
Put the 2 equations together:
12+2y=10+4y
<em>Subtract 10 from both sides</em>
2+2y=4y
<em>Subtract 2y from both sides</em>
2=2y
y=1
