Answer:
This can't really be factored, but it can be expanded slightly.
(3x³)³ = 27x⁹
Answer:
Step-by-step explanation:
Apply the Pythagorean Theorrem. Find the sum of the squares of the two shortest sides and determine whether this sum equals the square of the longest side:
#19: 5^2 + 12^2 = ? = 13^2
25 + 144 = ? = 169 This is true, so you do have a right triange in #19.
#21: 2^2 + 4^2 = ? = 7^2, or 4 + 16 = ? = 49 This is false. Not a right
triangle.
Apply this same approach (Pythagorean Theorem) to the remaining problems.
The expression "x is less than or equal to zero" can be written in several forms; some examples, however, could be:
x ≤ 0
0 ≥ x
(You could substitute any number in place of 3 for the below)
3 - 3 ≥ x
Answer:
Step-by-step explanation:
Yes it is the same. 1/4 +1/4 = 1/2. so 9/10-1/2=9/10-1/2
