Answer:

a) Yes

b) No

c) Yes

d) No

e) No

Step-by-step explanation:

Right triangle:

The square of the larger side is equals to the sum of the squares of the smaller sides.

a. 6, 8, 10

$6^2 + 8^2 = 36 + 64 = 100 = 10^2$

The answer is yes.

b. 8, 15, 16

$8^2 + 15^2 = 64 + 225 = 289 \neq 16^2 = 256$

So no.

c. 10, 24, 26

$10^2 + 24^2 = 100 + 576 = 676 = 26^2$

So yes

d. 20, 21, 28

$20^2 + 21^2 = 400 + 441 = 841 \neq 28^2 = 784$

So no.

e. 9, 35, 41

$9^2 + 35^2 = 81 + 1225 = 1306 \neq 41^2 = 1681$

What is the value of x, when x2 + 5 = 21?

djverab [1.8K]

Hey there!

$\bold{x^2+5=21}$
Firstly, subtract by the number $\bold{5}$ on each of your sides
$\bold{x^2+5-5=21-5}$
$\bold{Cancel:5-5}$ because it gives us the result of $\bold{1}$
$\bold{Keep:21-5}$ because it equals: $\bold{16}$
$\bold{x^2=16}$
Nextly, we have to take our square root
$\bold{x=}$ ± $\bold{\sqrt{16}}$
Solve the square root and you have found your answer
$\boxed{\boxed{\bold{Answer:x=4[or]x=-4}}}$ $\bold{\checkmark}$

Good luck on your assignment and enjoy your day!
