<h3>Solution:-</h3>

⟹( 4x + 3 )( 2x - 5 )

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

⟹8x²- ( - 20x ) + 6x - ( - 15 )

⟹8x² + 20x + 6x + 15

0.5s +1=7 + 4.5s S =

kvv77 [185]

Answer:

$s = -\frac{3}{2}$

Step-by-step explanation:

Solve for the value of $s$ :

$0.5s + 1 = 7 + 4.5s$

-Combine both $0.5s$ and $4.5s$ by subtracting $0.5s$ by $4.5s$ :

$0.5s + 1 - 4.5s = 7 + 4.5s - 4.5s$

$-4s + 1 = 7$

-Subtract $1$ to both sides:

$-4s + 1 - 1 = 7 - 1$

$-4s = 6$

-Divide both sides by $-4$ :

$\frac{-4s}{-4} = \frac{6}{-4}$

$s = -\frac{3}{2}$

So, the value of $s$ is $-\frac{3}{2}$ .
