Answer:
5
Step-by-step explanation:
5 > 0 (True)
Plug in 5 for t in the equation.
t² - 25 = 0
(5)² - 25 = 0
(5 * 5) - 25 = 0
(25) - 25 = 0
0 = 0 (true).

Answer:
C = -6
Step-by-step explanation:
C = [2×1/4 + 1] ÷ [3×1/4 -1 ]
C = 3/2 ÷ -1/4
C = 3/2 × -4 = -6
C = 2d + 1 / 3d - 1
So, d = ( C + 1 ) / ( 3C - 2 )
Answer:
oof the answer is c
Step-by-step explanation:
Sin 2 x + sin x = 0
( sin 2 x = 2 sin x cos x )
2 sin x cos x + sin x = 0
sin x ( 2 cos x + 1 ) = 0
sin x = 0
x 1 = 0
x 2 = π
or: 2 cos x + 1 = 0
2 cos x = - 1
cos x = -1/2
x 3 = 2π/3
x 4 = 4π/3
