Answer:
x=3 x = -1
Step-by-step explanation:
f(x) = x^2 − 2x − 3
Set the function equal to zero
0 = x^2 − 2x − 3
Factor
What two numbers multiply to -3 and add to -2
-3 *1 = -3
-3+1 = -2
0 = (x-3)(x+1)
Using the zero product property
x-3 =0 x+1 =0
x=3 x = -1
Sum/Difference of 2 monomials is (in simplest terms) a monomial when the 2 monomials are 'like terms
Answer:
14800
Step-by-step explanation:
Area of trapezoid =
Using the formula above, our equation will look like this:
145 + 225 = 370
370/2 = 185
185 * 80 = 14800
