Answer:

Value of a = 8

Value of b = 2

Value of c = - 10

Step-by-step explanation:

(2x + 3)(4x - 5)

=  > 2x(4x - 5) + 3(4x - 5)

=  > 8 {x}^{2}  - 10x + 12x - 15

=  > 8 {x}^{2}  + 2x - 10

As per the general form of a quadratic eqn. a {x}^{2}  + bx + c

Value of a = 8

Value of b = 2

Value of c = - 10

Answer:

-9A · √(5yA)

Step-by-step explanation:

The coefficient -3 stays the same.

45 factors into 5·9, which is helpful because 9 is a perfect square.

Thus, √45 = 3√5.

y cannot be factored.  It stays under the radical.

A³ can be factored into A² (a perfect square) and A.

Thus,

-3√(45yA³) = -3 · 3√5 · √y · A · √A, or

                   = (-3)(3)(A) · √(5yA), or

                    = -9A · √(5yA)

Select the correct answer.
adell [148]

Answer:

its c. x = -2.5 and x = -2

Step-by-step explanation:

multiply function (g)(x) = (-2x-5)(x-2)

= -2x^2+4x-5x+10

first get out -2x(x+2)-5(x+2)

(-2x-5) or (x+2) = 0

x=-5/2 or x=-2

its c that both points covered in that line of x axis
