X2-9x+ ___= 6

x2-9x+81/4=6

(This is because you need to do 2*x*a=-9x) Hence 2a=-9

So a=-9/2 hence a2= 81/4

216.4 is the total cost added up. 

198.77 would be the subtraction of the answer above with the hardware supplies but subtraction would be wrong so you'd have to divide, dividing would get you to 0.0814, the you'll have to divide the decimal by 100 giving you 0.0815.

Do the same steps above but with the paint and hardware. 

52.91/216.4 gives you 0.244501, rounded up would give you 0.000245.

Add those two totals together to get your answer, 0.081745.

Sorry if I'm wrong. Hope this helps!

3k=11-13

Calculate the difference
3k=-2
Divide both sides by 3

Andreyy89

Answer:

Obj B, by 1 g/cm^3

Step-by-step explanation:

Obj A = 12g / 8cm^3 = 3g / 2cm^3 = 1.5 g/cm^3

Obj B = 20g / 8cm^3 = 5g / 2cm^3 = 2.5 g/cm^3

2.5 - 1.5 = 1 g/cm^3
