Step-by-step explanation:
a. ( p × q ) ( q + r )
= ( -24 × 12 ) ( 12 + -6 )
= 288 × 18
= 5184
b. ( p × r ) ( r - q )
= ( -24 × -6 ) ( -6 - 12 )
= ( 144 ) ( -18 )
= -2592
So every 5 inches in height, there are 32 marbles. You want to know how many marbles there are per 18 inches in height.

To get from 5 to 18, you multiply by 3.6.
Do the same thing to the numerator; 32 × 3.6 = 115.2.
Since 0.2 marbles is no marbles, you round down.
There are 115 marbles in the box.

Answer:
1.5 + 1.3228756555323i
1.5 - 1.3228756555323i
Step-by-step explanation:
y = ax^2 + bx + c
a = 1, b = -3, c = 4
Using the quadractic formula:

Note: Kindly ignore the A in the above solution ^
Hence, there is no real solution. It has complex roots.
