Answer: 1482
Step-by-step explanation:
Each number in the series is greater than the previous number by 4.
(n/2) * (S + (S + ((n-1) * 4)))
where:
S = 7
n = 26
(26/2)× (7+(7+((26-1) ×4)))
(13)× (7+(7+(25)×4)
13×114
herefore, the solution is 13 * 114 = 1,482
You would want to start by putting like terms together.
3.2g² + 5.7g² + 5.7d - 2.7d - 4.2d
Now just simplify the terms
3.2g² + 5.7g² = 8.9g²
5.7d - 2.7d - 4.2d = 3d - 4.2d = -1.2d
Now you are left with 8.9g² - 1.2d which cant be simplified more.

Answer:
Step-by-step explanation:
hello :
cot x + 2cot x sin x = 0 0≤ x≤ 180
cotx(1+2sinx) =0 means : cotx=0 or 1+2sinx=0
1) cotx=0 so : cosx=0 and sinx ≠ 0 because cotx = cosx/sinx
when : 0≤ x≤ 180 : x=90°
2) 1+2sinx=0 means : sinx = -1/2
when : 0≤ x≤ 180 : no solutions because : sinx ≥ 0
conclusion : one solution : x=90°
