The angle is 60 degrees
Step-by-step explanation:
Answer:
Step-by-step explanation:
Rewrite this quadratic in standard form: 3x^2 + 7x - 1.
The coefficients of x are {3, 7, -1}, and so the discriminant is b^2 - 4ac, or
7^2 - 4(3)(-1), or 49 + 12, or 61. Because the discriminant is positive, this quadratic has two real, unequal roots
Answer:
-$336.00
Step-by-step explanation:
-$248.00+-$73.00+-$15.00=-$336.00
I do not know if you mean x² or 2x, so here are both equations:
Equation 1:
x² - 16 = 0
x² = 16
x = √16
x = <span>±</span>4
Solutions: x = 4 and x = -4
Equation 2:
2x - 16 = 0
2x = 16
x = 8
Solution: x = 8
The difference of squares is 4m^2 - 20mn + 25n^2
Its a perfect square trinomial.
<h2>What is
perfect square trinomial?</h2>
A perfect square trinomial is the square of a binomial. It follows a pattern when it is factored, so that the first and last terms are perfect squares of monomials and the middle term is twice their product. If the pattern does not fit for a particular trinomial, it is not a perfect square trinomial.
<h3>How to solve this equation?</h3>
(-2m + 5n)^2
(-2m + 5n)(-2m + 5n)
4m^2-10mn-10mn+25n^2
4m^2 - 20mn + 25n^2
Thus, the difference of squares is 4m^2 - 20mn + 25n^2
Its a perfect square trinomial.
