Can 4 cm, 7 cm, 9 cm be a right triangle

No

Step-by-step explanation:

For it to be a triangle c² = a² + b²

The longest side is c (9)

and 81 ≠ 49 + 16

Can I get brainliest

No

Step-by-step explanation:

Since it might be a right triangle, we can test the values using the Pythagorean theorem.

a and b are the legs, and c is the hypotenuse.

We know that 4 and 7 are the legs, or a and b. This is because they are two smaller sides.  We know that 9 is the hypotenuse, or c. This is because it is the longest side.

Solve the exponents

65=81

Since 65 does not equal 81, this cannot be a right triangle

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
