Answer:

Step-by-step explanation:
×
6 x 6 = 36
4 + 3 = 7 (add exponents because its multiplication)
Given:
The area model for
.
To find:
The value of
and the missing values in the area model.
Solution:
2.1 can be written as 2 and 0.1 on the left side of the area model.
3.2 can be written as 3 and 0.2 on the top of area model.
Area of the four parts of the area model are:




The complete area model is shown below.
After adding all areas of the area model, we get

Therefore, the value of
is 6.72 and the missing values of the area model are 0.3 and 0.02 respectively.
Start at 5 on the y axis then go down four and over 1
I think the lamp is 26.5? because maybe it is 25+1.50 since the first one was 8.00+0.48 I'm not sure about the others sorry:( I hope you'll get your answer though!
31) there are 12. The distance between them is 10-4=6. This is halfway around so there are 12 (think of a clock face, 4 is opposite 10 and there are 12 numbers.)
