If you’re looking for the answer it’ll be 0
30-40= -10
-10+10= 0
The value of x which would make that equation true is 7
8 Is you're answer! hope that i helped!
Answer:
- 8
Step-by-step explanation:
Given
x² - 64 = 0 ( add 64 to both sides )
x² = 64 ( take the square root of both sides )
x = ± = ± 8
Solutions are x = 8 and x = - 8
Answer:
Step-by-step explanation:
The area of a triangle is given by where is the base of the triangle and is the height of the triangle. In a right triangle, the two legs will represent the base and height, both interchangeable.
In a 30-60-90 triangle, the sides are in the proportion , where is the hypotenuse of the triangle and is the side opposite to the 30 degree angle. Since the hypotenuse of this triangle is given as 10, the leg opposite to the 30 degree angle is equal to and the leg adjacent to the 30 degree angle is equal to .
Thus, the area of this triangle is equal to:
