Find the solutions to x2 = 28.
mr Goodwill [35]

Answer: x = \pm2\sqrt{7}\\\\

Work Shown:

x^2 = 28\\\\x = \pm\sqrt{28}\\\\x = \pm\sqrt{4*7}\\\\x = \pm\sqrt{4}*\sqrt{7}\\\\x = \pm2\sqrt{7}\\\\

This can be rewritten into x = 2\sqrt{7} \ \text{ or } \ x = -2\sqrt{7}

Ostrovityanka [42]

Answer:

The height of Mrs. Marigold's roof is 10 feet.

Step-by-step explanation:

Given that,

Base of the given triangle = 48 ft

Hypotenuse = 26 ft

Half of the base = 24 ft

Using Pythagoras theorem,

h=\sqrt{26^2-24^2}\\\\h=10\ ft

So, the height of Mrs. Marigold's roof is 10 feet.

which set of side lengths form a right side?a) 3ft,6ft,5ft b)50 in,48in,14in c)53m,48m,24m d)8cm,17cm,14cm​
muminat

Answer:

<h2>b) 50in, 48in, 14in</h2>

Step-by-step explanation:

If <em>a ≤ b < c</em><em> </em>form of a right side, then <em>a² + b² = c²</em>

a) 3ft, 6ft, 5ft

3² + 5² = 6²

9 + 25 = 36

34 = 36        <em>FALSE</em>

b) 50in, 48in, 14in

14² + 48² = 50²

196 + 2304 = 2500

2500 = 2500     <em>CORRECT :)</em>

c) 53m, 48m, 24m

24² + 48² = 53²

576 + 2304 = 2809

2880 = 2809     <em>FALSE</em>

d) 8cm, 17cm, 14cm

8² + 14² = 17²

64 + 196 = 289

260 = 289    <em>FALSE</em>
