I NEED HELP I AM STUPID SO I DONT GET THIS HERE IS THE QUISTION 4-x-6(x+5)=15 HE ALSO SAID THIS - Students will determine whether an equation has 0, Infinite, or 1 solution, and if 1, find it. I ADDED A SCREEN SHOT OF QUISTION PLS HELP ME OR I AM FAILING THIS CLASS

im pretty sure it has two real solutions

Step-by-step explanation:

1. simplify the equation given

  (4x - 6)(x + 5) = 15

     4x^2 + 20x - 6x - 30 = 15

        4x^2 + 14x - 45 = 0

2. find the discriminant (b^2 - 4ac); (a = 4, b = 14, c = -45)

  14^2 - (4 x 4 x -45)

     196 - (-720)

        916

  the discriminant is positive, so this equation has 2 real solutions

to find the solutions, factor the bolded equation (if you need help factoring, let me know!)

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
