Let x=balloon swords
let x+4=balloon dogs (four more than x is x+4)
let x+7=balloon hats (three more than x+4 is x+7)
the answer is x+7
I don't know how to correctly explain the second answer (although I do know that it is 1)
Answer:
A and C
Step-by-step explanation:
Given
2cos²x - 2 = 0 ( add 2 to both sides )
2cos²x = 2 ( divide both sides by 2 )
cos²x = 1 ( take the square root of both sides )
cos x = ±
= ± 1
cos x = 1 ⇒ x =
(1) = 0°
cos x = - 1 ⇒ x =
(- 1) = 180°
Answer:
c
Step-by-step explanation:
Answer:
x = -1
Step-by-step explanation:
3(x+2)=−5−2(x−3) multiply 3 and -2 with inside the parenthesis
3x + 6 = -5 -2x + 6 now add the like terms
3x + 2x = 1 - 6
5x = -5 simplify both sides
x = -1
