There are 12 inches in a foot.
Divide 94 by 12.
94 / 12 = 7.8333
So there are 7 feet and a few inches.
Now we multiply 12 to 7.
12 * 7 = 84
Subtract this from 94.
94 - 84 = 10
So there are 7 feet and 10 inches in 94 inches.
Answer:
v×w = -6i-12
Step-by-step explanation:
hello :
Let v=-3i and w=2 - 4i.
v×w = -3i(2-4i) = -6i+12i² = -6i-12 ... i² = -1
The combined area of these three rooms is 189 ft².
Therefore we have the equation
4x + 3x + 2x = 189
9x = 189 |:9
x = 21 ft²
area of the kitchen = 4x = 4(21) = 84 ft²
area of the playroom = 3x = 3(21) = 63 ft²
area of the dinning room = 2x = 2(21) = 42 ft²
