The equation is y=-2/5x+7 3/5
Hi there!
I'm going to assume you mean m^2 + m - 20.
The factor of this is (m + 5)(m - 4)
And I found this by finding what two numbers add to 1 and multiply to -20, which is 5 and -4.
Now if you FOIL this, (First, outer, inner, last terms) you should come to the initial equation.
(m + 5) * (m-4)
m * m = m^2
5 * m = 5m
m * -4 = -4m
5 * -4 = -20
So, in combining like terms, you'd get m^2 + 1m -20.

Answer: 45
Step-by-step explanation:
Step-by-step explanation:
true duh just use calculator
The solution would be like this for this specific problem:
<span>Area = L * W = 600
Length = W + 25</span>
<span>Substitute and solve for "W":
(W + 25)W = 600</span>
<span>
w^2 + 25w - 500 = 0
(w - 15) (w + 40) = 0
Positive solution:
Width = 15 meters
Length = 15 + 25 = 40 meters</span>
<span>So, the dimensions of the playground using an
algebraic solution is 15 meters by 40 meters.</span>
To add, the minimum number of coordinates needed to
specify any point<span> within it is the informal definition of the dimension
of a mathematical space.</span>
