Subtract 8 from both sides

-3x < 15 - 8

Simplify 15 - 8 to 7

-3x < 7

Divide both sides by -3

= x > -7/3

C. -0.5, -1.5

Step-by-step explanation:

Given equation

4d^2+8d+3=0

To solve for

As the above equation is of 2nd degree, so its a quadratic equation. We can solve is by using quadratic formula.

For a quadratic equation ax^2+bx+c=0

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

So, for 4d^2+8d+3=0

$d=\frac{-8\pm\sqrt{8^2-4(4)(3)}}{2(4)}$

$d=\frac{-8\pm\sqrt{64-48}}{8}$

$d=\frac{-8\pm\sqrt{16}}{8}$

$d=\frac{-8\pm4}{8}$

So $d=\frac{-8+4}{8}$ and $d=\frac{-8-4}{8}$

$d=-\frac{1}{2}$ and $d=-\frac{3}{2}$

Or d=-0.5 and d=-1.5

∴ d= -0.5, -1.5
