Answer:
k = 25
Step-by-step explanation:
(2x - sqrt(k) )^2 Expand this as a binomial
4x^2 - 4x*sqrt(k) + k The middle term must be -20x Solve for k so it is
-4xsqrt(k) = - 20x Divide by -4x
sqrt(k) = -20x/-4x Do the division
sqrt(k) = 5 Square both sides
k = 25
Answer:

Answer:
20 years
Step-by-step explanation:
20 is the lowest common multiple for 5,4,2
A conjunction is a word that joins words or phrases. <em>For, and, nor, but, or, yet, so...</em>The conjunction in this sentence would be and.
(<em>most</em> is an adverb, <em>wow</em> is an interjection, and <em>of</em> is a preposition)
X= a number
If 52 is 130% of a number, then we multiply the unknown number by 130%.
x * 130%= 52
convert % to decimal (130%÷100)
1.3x= 52
divide both sides by 1.3
x= 40
ANSWER: The unknown number is 40, so it is less than 52. We multiply the unknown number by 130% to equal 52.
Hope this helps! :)
