Answer:
20
Step-by-step explanation:
The answer is 38 degrees because for every triangle, the angles add up to 180 and the small square on the triangle represents it is a right triangle, which has 90 degrees. 38 + 52 + 90 = 180
Answer:
ab=9 and ac=12
Step-by-step explanation:
Answer:
- (√30 - 1, 0)
- (-√30 - 1, 0)
Step-by-step explanation:
Making the equation of the parabola :
⇒ y = a(x - h)² + k
⇒ y = (x + 1)² - 17 - 13
⇒ y = (x + 1)² - 30
x-intercepts have y = 0 :
- 0 = (x + 1)² - 30
- (x + 1)² = 30
Taking the square root on each side :
- √(x + 1)² = √30
- x + 1 = ±√30
- x = ±√30 - 1
The x-intercepts are :
- (√30 - 1, 0)
- (-√30 - 1, 0)
The answer is:
545>322
540 <997
