(-2)to the 8th power = (-2) (-2) (-2) (-2)(-2)(-2)(-2)(-2) =258
Answers
Answer:
the answer to this would be 256.
Step-by-step explanation:
before explaining this,
- negative x negative = positive
- positive x positive = positive
- negative x positive = negative
- positive x negative = negative
this would be because -2 x -2 it equals 4. then, we multiply 4 x -2 and we get -8, then we multiply -8 x -2 and we get 16, then we keep doing the same thing until we get the answer/ used all the -2's.
1. -2 x -2 = 4
2. 4 x -2 = -8
3. -8 x -2 = 16
4. 16 x -2 = -32
5. -32 x -2 = 64
6. 64 x -2 = -128
7. -128 x -2 = 256

If we express distances as following:
T - total distance
a - distance from San Antonio to Austin
b - distance from Austin to Waco
c - distance from Waco to Dallas
Then:
T = 280 mi
b = a - 30 mi ⇒ a = b + 30
b = c + 20 mi ⇒ c = b - 20
T = a + b + c
⇒ a + b + c = 280
⇒ b + 30 + b + b - 20 = 280
⇒ 3b +10 = 280
⇒ 3b = 280 - 10
⇒ 3b = 270
⇒ b = 90 mi.
Distance from Waco to Dallas is c.
c = b - 20
⇒ c = 90 - 20
⇒ c = 70 mi
Therefore, distance from Waco to Dallas is 70 miles.
