Answer:
3 sqrt 5 ( or 6.7082039 as posted in earlier A )
Step-by-step explanation:
sqrt ( 5) ( 5-2) = 3sqrt 5
3 boxes of 12″ =36 = 2 boxes of 18″
so shortest height at which the 2 stack will be the same height =36 inches

Answer:
(10, - 9 )
Step-by-step explanation:
Given the 2 equations
y = - 2x + 11 → (1)
y = - 3x + 21 → (2)
Substitute y = - 2x + 11 into (2)
- 2x + 11 = - 3x + 21 ( add 3x to both sides )
x + 11 = 21 ( subtract 11 from both sides )
x = 10
Substitute x = 10 into either of the 2 equations and evaluate fir y
Substituting into (1)
y = - 2(10) + 11 = - 20 + 11 = - 9
solution is (10, - 9 )
Answer:
We know that a negative value is positive of all even exponents and negative for all odd exponents.
y=(-1)^x
