Answer:
2sqrt(2)
Step-by-step explanation:
5x^2 - 40 = 0
=> 5x^2 = 40
=> x^2 = 40/5 = 8
=> x = sqrt(8) = sqrt(4 x 2) = 2sqrt(2)
Answer:
D natural, whole, integar, rational
Answer:
3
Step-by-step explanation:
To the tenth term in the sequence we need to change all the n's to 10.
so...
a₁₀ = 4 + ( -1 )¹⁰ =
4 + (-1) = (Because -1¹⁰ = -1)
4 - 1 = 3
Answer:
The expression representing the perimeter of the platter will be:
P = 10/3x units
Hence, option (D) is true.
Step-by-step explanation:
Let the length l of a rectangular platter will be = x
As the width of a rectangular platter is 2/3 its length.
so the width w of a rectangular platter will be = 2/3x
As the perimeter of the platter is defined as:
P=2(l+w)
where l is the length, and w is the width
substituting length l = x and width w = 2/3x

∵ 
units
Therefore, the expression representing the perimeter of the platter will be:
P = 10/3x units
Hence, option (D) is true.
