9/10 because that equals .9
The evaluation of the algebraic fraction x+2x+1/x^2-25 is
<h3>What is the division of algebraic expression?</h3>
The division of an algebraic expression can be carried out by using the long division method or expansion of the.
Given that:
where:
By expanding the denominator, we have:
Creating a partial fraction from the denominator, we have:
Multiply the equation by the denominator, and we have:
Simplifying, we have:
3x + 21 = a₀(x-5)+a₁(x+5)
Solve for the unknown parameter by plugging the real roots of the denominator: -5, 5
Replacing the solutions into the partial fractions parameters to obtain the final result, we have:

Answer:
The inequality x>2 matches the graph.
Step-by-step explanation:
From the graph, it is clear that the shaded graph is heading towards the +ve infinity from the x > 2.
If the inequality includes < or >, we graph the equation as a dotted line.
From the graph, the dotted line indicates that x=2 is not included in the solution of the inequality.
so the interval of the domain of the inequality is: (2, ∞)
Therefore, the inequality x>2 matches the graph.

Step-by-step explanation:
area of a trapezoid :
where a and b = length of bases and h = height
here, we are given the area, the length of one base and the height
we want to find the other base length
we can do this by plugging in what we are given and then solving for the unknown variable
first lets define our known variables
Area (A) = 42 , height (h) = 4 and length of one of the bases (a) = 9
we then plug this into the formula and solve for b, the other base length
recall formula :
A = 42 , h = 4 , a = 9
now solve for b
divide both sides by 4
multiply both sides by 2
21 = 9 + b
subtract 9 from both sides
12 = b
the other base length is 12
