In matrix form, this is

The coefficient matrix has determinant

so it has an inverse, which is

Multiply both sides by the inverse matrix:


so that
and
.
Answer:x+21
Step-by-step explanation:
4096 ways : 8 candy toppings plus 4 fruit toppings is 12. Then 2^12 (2 different types of toppings and the 12 of total toppings) = 4096
1 foot = 12 inches
(1 foot)³ = (12 inches)³
12³ = 1,728 in³
To change 10 cubic feet into cubic inches
10 ft³ * 1728 in³/ft³ = 17,280 in³ Choice C. Multiply by 1,728
Multiplying or dividing two related quantities by the same number is called scaling
