Answer:
Step-by-step explanation:
Answer:
E. 64,000,000
Step-by-step explanation:
2^26 = (2^13)^2
But 2^13 = 8000 so
2^26 = (8,000)^2
= 64,000,000
Step-by-step explanation:
let d+e=2 be equation 1
let d-e=4 be equation 2
lets make d the subject in equa 1
d = 2-e equation 3
put equation 3 in 2
2-e=4
e=2-4
e=-2
put e=-2 in equa 1
d-2=2
d=4
e is -2 and d is 4
Simplify the following:
-3 x^2 + 2 y^2 + 5 x y - 2 y + 5 x^2 - 3 y^2
Grouping like terms, -3 x^2 + 2 y^2 + 5 x y - 2 y + 5 x^2 - 3 y^2 = (2 y^2 - 3 y^2) + 5 x y - 2 y + (5 x^2 - 3 x^2):
(2 y^2 - 3 y^2) + 5 x y - 2 y + (5 x^2 - 3 x^2)
2 y^2 - 3 y^2 = -y^2:
-y^2 + 5 x y - 2 y + (5 x^2 - 3 x^2)
5 x^2 - 3 x^2 = 2 x^2:
Answer: -y^2 + 5 x y - 2 y + 2 x^2
