Answer:9x-9=7 or 9x-9=-7
Step-by-step explanation:
An absolute value is the distance from zero, therefore the answer can not be negative. In this case, 9x-9=7 and 9x-9=-7 both work, because 7 and -7 are the same distance from zero.
Answer:
1.024x10^17
Step-by-step explanation:
5^5(16^2x5^3)^3
find the 5^5
3125(16^2x5^3)^3
distribute the power of 3 into the parentheses
3125(16^6x5^9)
multiply
3125(16777216x1953125)
1.024x10^17
All you have to do here is combine like terms.
5x + 9x = 14x
.5 - 2.5 = -2
14x - 2
P,Q,R can't be 0, because their product is nonzero. Either of S and T could be 0, but the third one only works if S is 0.
