Answer:
84
Step-by-step explanation:
Surface area is the combined area of the 2 dimensional planes.
6 × 5 + 3 × 4 × 1/2 × 2 + 6 × 3 + 4 × 6
30 + 12 + 18 + 24
= 84
The surface area is 84 square centimeters.
Which ever expression is 3x + 21 + 10 ..... 21 + 10 = 31 .... So it'll be 3x + 31 .
C because if you add them all together
Answer:
3
Step-by-step explanation:
Points A and B lie on the horizontal line y = 1. The length of segment AB is then the difference of the x-coordinates of the points:
5 -2 = 3
The length of side AB is 3 units.
- if you simplify it you would have to find factors of 45 that are perfect squares, for example, the square root of 9 times the square root of 5 is the square root of 45 so if you want to simplify it you would need to take the square root of 9 which is 3
so if you put in simplest form you would get 3 root 5
