-9x^2 + x - 7 = 0
Answers
Answer:
0 real roots
Step-by-step explanation:
Given a quadratic equation in standard form
ax² + bx + c = 0 ( a ≠ 0 )
Then the discriminant is
Δ = b² - 4ac
• If b² - 4ac > 0 then 2 real and distinct roots
• If b² - 4ac = 0 then 2 real and equal roots
• If b² - 4ac < 0 then the roots are not real
- 9x² + x - 7 = 0 ← is in standard form
with a = - 9, b = 1, c = - 7 , then
b² - 4ac = 1² - (4 × - 9 × - 7) = 1 - 252 = - 251
Since b² - 4ac < 0 then the equation has no real roots

Answer:
sqrt (2) * sqrt(45) + sqrt (2) * sqrt (80)
45 = 9 *5 "9" is a perfect square so
sqrt (45) = 3 * sqrt (5) * sqrt (2)
sqrt (2) * sqrt (80)
80 = 16 * 5 "16" is a perfect square so
sqrt (2) * sqrt (80) = sqrt (2) * 4 * sqrt(5)
Adding both answers we get
3 * sqrt (5) * sqrt (2) = 3 * sqrt(10)

What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
The reason for this order is that an equilateral triangle has all three sides equal in length, while an isosceles triangle has two sides equal in length and one side different.
A scalene triangle has all three sides of different lengths.
Since all three sides of an equilateral triangle are equal, it has the smallest perimeter of the three types of triangles.
The isosceles triangle has two sides equal, so its perimeter will be greater than that of an equilateral triangle, but less than that of a scalene triangle.
Finally, the scalene triangle has three sides of different lengths, so it will have the largest perimeter of the three types of triangles.
Thus,
The triangles with equal sides from least to greatest
Equilateral, Isosceles, Scalene.
