Answer:
6x^3-33x^2+45x-6
Step-by-step explanation:
The formula for the perimeter of a square is P = 4s, where s is the length of one of the four (4) congruent sides of the square.
The formula for the area of a square is A = s², and we're given that the area of a square, whose perimeter we're trying to find, is 36 sq. units; therefore, we have:
A = s²
36 sq. units = s²
√(36 sq. units) = √s²
6 units = s (Note: We used the positive square root (6) rather than the negative square root (-6) since you physically can't have a negative length!)
Therefore, ...
P = 4s
P = 4(6 units)
P = 24 units is the perimeter of a square whose area is 36 square units
Answer:
30
Step-by-step explanation:
The sum of all the angles in a triangle is always, always, 180 degrees.
Just add the angles, then solve for x.
(2x - 10) + (x + 30) + 70 = 180
3x + 20 + 70 = 180
3x + 90 = 180
3x = 90
x = 30
