Which factors can be multiplied together to make the trinomial 5x2 + 8x – 4? Select two options. (x + 1)
(2x + 1)
(x + 2)
(5x + 1)
(5x – 2)

c) (x +2)

e) ( 5 x -2)

Step-by-step explanation:

Explanation:-

Given equation  5 x² + 8 x – 4

The factors of  - 20 = 10 × - 2

                   ⇒      5 x ² + 10 x - 2 x - 4

                    ⇒      5 x ( x + 2) - 2 ( x + 2)

                     ⇒     (5 x - 2 ) ( x + 2)

The multiplies of given equation

                           5 x² + 8 x – 4 =   (5 x - 2 ) ( x + 2)

answer is b

step-by-step explanation:

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
