32(40-4)
32*40 - 32*4
1,280 - 128=
1,152
therefor
32*36= 1,152
Answer:
The second equation is correct.
y=2.25x + 4
Step-by-step explanation:
We can systematically eliminate the others.
For equation 3 and 4, 6.5*2 and 12*x is already bigger than 8 of the first set of numbers.
For equation 1, 2*x+8.5 is also bigger than 8 from the first set.
Plugging in the values to equation 2, we always get the correct cost.
2 to the power of 6 or 4 to the power of 3
it cannot be simplified, only rounded. THis rounded as a fraction is "7 7/10"
