Answer:
x = 6
Step-by-step explanation:
Given
6x² - 2x + 36 = 5x² + 10x ( subtract 5x² + 10x from both sides )
x² - 12x + 36 = 0 ← in standard form
This is a perfect square of the form
(x - a)² = x² - 2ax + a²
36 = 6² ⇒ a = 6 and 2ax = (2 × 6)x = 12x, hence
(x - 6)² = 0
x - 6 = 0 ⇒ x = 6
3 to the power of 5
you multiply 3 times 5 instead of 3 times 3 times 3 times 3 times 3

70000000 the reason that this is the answer to this is because if multiply 10 by 7 you will have 70 and just add 6 zeros
Answer:
x = 100
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
52 + 28 + x = 180
80 + x = 180 ( subtract 80 from both sides )
x = 100
