A perfect square is a number made by squaring a whole number.
Since
numbers 1, 16, 100 are perfect squares. You cannot find such whole number n, that
therefore, numbers 2, 18, 32, 44, 94 are not perfect squares.
Answer: 1, 16, 100.
X = 0.4/3
x = 13
if answer is wanted in decimal form.
Answer:
C.
Step-by-step explanation:
To find the area of a triangle, one must multiply the base by the height then divide by 2.
So, the area of this triangle would be 7.5
Answer:
7x²sqrt(x)
Step-by-step explanation:
7x^(5/2)
7x^(2½)
7x^(2+½)
7x² × x^½
7x²sqrt(x)
sqrt: square root
√52 -√13 +√117
= 2√13 -√13 +3√13
= 4√13 . . . . matches selection A
_____
√52 = √(4·13) = (√4)(√13) = 2√13
√117 = √(9·13) = (√9)(√13) = 3√13
