Answer:

x = 25

Step-by-step explanation:

If JK and MN are parallel lines, then ∠JKL = ∠LMN = 61°

By the opposite angle rule, ∠JLK = 39°

In a triangle three angles sum up to 180°

so, ∠JLK + ∠JKL +LJK = 180°

39° + 61° + 3x+ 5 = 180°

3x = 75

x = 25

5. f(x) = 3x³ - 4x² +6x and g(x)=5x ³+ 2x²- 3x. What is f(x) - g(x)?
sasho [114]

Answer:

<h2>A. -2x³ - 6x² + 9x</h2>

Step-by-step explanation:

f(x)=3x^3-4x^2+6x\\\\g(x)=5x^3+2x^2-3x\\\\f(x)-g(x)=(3x^3-4x^2+6x)-(5x^3+2x^2-3x)\\\\=3x^3-4x^2+6x-5x^3-2x^2-(-3x)\qquad\text{combine like terms}\\\\=(3x^3-5x^3)+(-4x^2-2x^2)+(6x+3x)\\\\=-2x^3-6x^2+9x

Goshia [24]

Answer:

let cp be x

mp= x+ (20% 0f x)= 1.2x

sp = mp -d%of mp= 1.2- 15% *1.2 =1.02x

profit = 40

sp-cp =40

1.02x-x=40

x=2000

cp =2000

mp= 1.2*2000=2400

What is the value of a and b F(x)=x(x+a)(x-b)
nalin [4]
Unfortunately, Tashara, you have not provided enuf info from which to calculate the values of a and b.  If you were to set  <span>F(x)=x(x+a)(x-b)  = to 0, then:

x=0,
x=-a
x=-b

but this doesn't answer your question.
Double check that you have shared all aspects of this question.</span>
