<h2>Answer:</h2><h2>g = 2  and h = -5</h2>

Step-by-step explanation:

To find the product with unknown values of variables, multiply the terms and equate the value to the given product.

(7d^{2} - 3d + g)(3d^{2} + hd - 8) = 21d^{4}  + 7hd^{3} - 56d^{2} - 9d^{3} - 3hd^{2} + 24d + 3gd^{2} + ghd - 8g

(7d^{2} - 3d + g)(3d^{2} + hd - 8)     = 21d^{4}  + (7h-9) d^{3} + (3g-56-3h)d^{2}  + (24+gh)d -8g   ... (1)

Comparing eq(1) to the product given in question,

-8g = -1

g = 2

24 + gh = 14, sub g =2,

24 + 2h = 14

h = -5

4x9=36

x=36

elena55 [62]

Answer:

Divide each side by V

n = C/V = 48/(⅜)

Invert the fraction and multiply

n = 48 × ⁸/₃

Cancel 3s

n = 16 × 8  

Multiply

n = 128

Ryan can eat pancakes 128 times from his giant bottle without running out of syrup.
