I believe its already in standard form so you would just add it
It’s -5^10 because, since the exponent is an even number, the number has to come out positive no matter the positive or negative value of its base. (This would change if the exponent was an odd number) And since 5^10 is of a greater value than 5^9, -5^10 is the correct answer.
One solution
11x + 25 = 7x+15
-7x -7x
4x+25=15
-25 -25
4x= -10

x= -10/4
-10/4 simplified is -5/2
so there is one solution where x=-5/2

<span>Change 5'9" to 5.75 ft; let t = height of the tree
</span><span>You can use ratio here (corresponding sides of similar triangles):
5 x 75/ 5 = t/165
</span><span>cross multiply
5t = 5.75*165
5t = 948.75
t = 948.75/ 5

Area of rectangle = length × width
300 = (x+10) × x
300 = 10x + x^2
Now we have the equation y=x^2 + 10x - 300
We can factor this equation to get our zeroes, which are:
-5(1+sqrt(13)),
5(sqrt(13)-1)
We only use the positive zero because we can't have a negative dimension.
Your width would be:
5(sqrt(13)-1)
Your length would be:
5(sqrt(13)-1) + 10
