Answer:
- Line XY is a line
- Distance XY is the length between the two letters.
Step-by-step explanation:
- When there's a line over two letters, that is a line.
- When there's nothing above the two letters. it is the length between the two points on the line.
Be very careful with these two meanings.


So we are to merge the two equations into one, since both of the equations are equal to y. a = b, b = c therefore, a = c.

We are to isolate x.
![x[tan(72)-tan(55)]=2.2tan(55)](https://tex.z-dn.net/?f=x%5Btan%2872%29-tan%2855%29%5D%3D2.2tan%2855%29)

The value of x is approximately, 1.9047m
Then, substitute the value of x from


y = 5.862m
Round up, then the answer would be D.

Step-by-step explanation:
solution:
total suface area of the pyramid
=area of base square +(12)2 = 4 (1/2 x 12 x 8)
=144+192
=336ft2
then the total surface area is 336ft2
Answer:
2
- 16
+ 18
Step-by-step explanation:
Given
(a²)(2a³)(a² - 8a + 9) ← multiply the first 2 factors
= 2
(a² - 8a + 9) ← distribute the parenthesis by 2
= 2
- 16
+ 18
