azamat

Answer:

=3

=2

Step-by-step explanation:

12−5+6=0

using the Quadratic Formula where

a = 1, b = -5, and c = 6

=−±2−4‾‾‾‾‾‾‾‾√2

=−(−5)±(−5)2−4(1)(6)‾‾‾‾‾‾‾‾‾‾‾‾‾‾√2(1)

=5±25−24‾‾‾‾‾‾‾√2

=5±1‾√2

The discriminant 2−4>0

so, there are two real roots.

Simplify the Radical:

=5±12

=62=42

which becomes

=3

=2

hope this helps :)

7. Given a right triangle as shown below, use a calculator to estimate the length of the
Wewaii [24]

Answer:

D. 11.6 cm

Step-by-step explanation:

The missing length of the right angled triangle can be calculated using Pythagorean Theorem as shown below:

c^2 - b^2 = a^2

Where,

a = x cm

b = 11 cm

c = 16 cm

Thus:

16^2 - 11^2 = x^2

256 - 121 = x^2

135 = x^2

\sqrt{135} = \sqrt{x^2}

\sqrt{135} = x

11.61895 = x

x = 11.6 cm (nearest tenth)
