Amiraneli [1.4K]

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.

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

erica [24]

Answer:

The distributive property of multiplication

Step-by-step explanation:

<u>explanation</u>:-

The distributive property of multiplication states that when a number is multiplied by the sum of two numbers, the first can be distributed to both of those numbers and multiplied by each of them separately,then adding the two products together for the same result as multiplying the first number by sum.

a(b+c) = a.b + a.c
