3 sides of the triangle are distinct perfect squares. What is the smallest possible perimeter of the triangle?
alisha [4.7K]

Answer:

77

Step-by-step explanation:

At first, you would probably think that the side lengths are 1², 2², 3² = 1, 4 and 9 but these side lengths don't form a triangle. The Triangle Inequality states that the sum of the two shortest side lengths must be greater than the largest side length, and since 1 + 4 > 9 is a false statement, it's not a triangle. Let's try 2², 3², 4² = 4, 9, 16. 4 + 9 > 16 is also false so that doesn't work. 3², 4², 5² = 9, 16, 25 but since 9 + 16 > 25 is false (25 isn't greater than 25), that doesn't work either. 4², 5², 6² = 16, 25, 36 and since 16 + 25 > 36 is true, this is our triangle which means that the perimeter is 16 + 25 + 36 = 77.

What is the equation for the graph shown?
Kamila [148]

Answer:

y = 2x/3 + 4

Step-by-step explanation:

The line passes through (-6, 0) and (0, 4)

slope = (4 - 0)/(0 - (-6)) = 4/6 = 2/3

y = (2/3)x + b

when x = 0, y = 4, so

4 = (2/3)*0 + b

b = 4

so

y = 2x/3 + 4

How do we Simplify each sum
Grace [21]

Answer:

The answer is 10m² - 1

Step-by-step explanation:

1) Remove parentheses.

{4m}^{2}  -  {5m}^{4}  - 5 +  {5m}^{4}  +  {6m}^{2}  + 4

2) Collect like terms.

( {4m}^{2}  +  {6m}^{2} ) + ( -  {5m}^{4}  +  {5m}^{4} ) + ( - 5 + 4)

3) Simplify.

{10m}^{2}  - 1

<u>Therefor</u><u>,</u><u> </u><u>the</u><u> </u><u>answer</u><u> </u><u>is</u><u> </u><u>10m</u><u>²</u><u> </u><u>-</u><u> </u><u>1</u><u>.</u>
