\[\sum_{n=1}^{7} 2(-2)^{n-1}\]
The scale factor 0.05 refers to length, so for area the scale factor is 0.05²=0.0025.
We then multiply: 220 ft²*0.0025=0.55 ft² (choice A)

Answer:
x=51
Step-by-step explanation:
There are two ways you can go about this
You can either say that the sum of interior angles in a triangle is equal to 180 so you do 180-39-90=51
Or you could use the exterior angle theorem, which means that 90=39+x, simplify that and you get that x=51
Answer:
B
Step-by-step explanation:
Given
7x - 9 > 2x + 6 ( subtract 2x from both sides )
5x - 9 > 6 ( add 9 to both sides )
5x > 15 ( divide both sides by 3 )
x > 3 → B
