Use the distributive property. For the first set of parenthesis, multiply everything inside by 8. This gets you to 8x-8.

Next set: Everything inside by 3x: 12x+3x^2.

Next set: Everything inside by 6: 6x+12.

Put it all together: 8x-8-12x+3x^2+6x+12-3.

Combine like terms: 2x+1+3x^2

19)  15/a = 3/2 

Start by cross multiplying....

3a = 30 

Divide both sides 3 

a = 10 

21)   2/7 = 4/d 

        2d = 28
       
        d= 14 

23)  8/p = 3/10

       
80 = 3p
         p = 26.66

25)  2 / -5 = 6/t
        2t = -30

      t = -15

Samuel has an ant farm with a volume of 375 cubic inches. The width of the ant farm is 2.5 inches and the length is 15 inches. W
Alexxandr [17]

Answer:

Step-by-step explanation:

From the given information, it is clear that the shape of ant form is rectangular prism.

Let us write formula for volume of rectangular prism (ant form)

V = l x w x h

Use the formula to write an equation.

Plug V = 375, w = 2.5 and l = 15

375 = 15 x 2.5 x h

375 = 37.5 x h

Divide both sides of the equation by 37.5

375/37.5 = (37.5 x h)/37.5

10 = h

Hence, the height of the form is 10 inches.
