Answer:
-15
Step-by-step explanation:
6.8(6.7 – 7.2) – 2(4.6 + 1.2)
The first step in PEMDAS is to do whatever's in the parenthesis. So, this would be the 6.8 bit.
6.8 times 6.7 is 45.56 and then 6.8 times 7.2 which is 48,96
Now we can also do the second set of parenthesis. 2 times 4.6 is 9.2, and 2 times 1.2 is 2.4
The equation now reads- (45.56 - 48.96) - (9.2 + 2.4)
All we have to do is evaluate what's in the parenthesis, the first set equals -3.4 and the second set equals 11.6
So, now our expression reads, -3.4 minus 11.6 which equals -15

Answer:
7
Step-by-step explanation:
The scale factor is how much something is increased by or decreased by.
From the question you can see that the sculpture is 49cm while the model is 7cm length wise
49/7 = 7
When you look at how wide it is it
35/7 = 7
When you look at how tall it is
63/9 = 7
Therefore the scale factor of the model to the sculpture is 7
