Answer:
X is...
Step-by-step explanation:
10x – 3 + x < 30
11x - 3 < 30 (add the one x to the 10)
11x < 33 (add the 3 to the 30)
x < 3 (divide both sides by 11 and the final number is the answer)
Answer:
yes, this sequence is arithmetic
Step-by-step explanation:
This is a 3-4-5 triangle.
Remember,
SOH-CAH-TOA
S(ine) = O(pposite)/H(ypotenuse)
C(osine) = A(djacent)/H(ypotenuse)
T(angent) = O(pposite)/A(djacent)
In Cosine, the adjacent = 3, and the Hypotenuse = 5
Hypotenuse is the longest side.
3,4,5 is the triangle that fits inside, therefore, the Opposite is 4, and Adjacent is 3
T(angent) = O(pposite)/A(djacent)
Plug in the numbers
T = 4/3
tan = 4/3 is your answer

Area is length times width.
Just some more info, volume is length times width times height.
Hope this helps!
