Step-by-step explanation:

<u>Step 1: Define</u>

3t + 7 = 2 + 5t

<u>Step 2: Solve for </u><u><em>t</em></u>

  1. [Subtraction Property of Equality] Isolate <em>t</em> terms:                                        7 = 2 + 2t
  2. [Subtraction Property of Equality] Isolate <em>t</em> term:                                         5 = 2t
  3. [Division Property of Equality] Isolate <em>t</em>:                                                        5/2 = t
  4. Rewrite:                                                                                                             t = 5/2

Elinor determined that a triangle with side lengths 6, 10, and 8 does not form a right triangle.62 + 102 = 8236 + 100 = 64136 ≠
weeeeeb [17]

Answer:

Option 3rd is correct

No,

she should have added 6^2 and 8^2 and compared that to 10^2

Step-by-step explanation:

In a right angle triangle, we use Pythagorean theorem.

Pythagorean theorem states that

the sum of the squares of two sides must equal the square of the third side(the side facing the right angle).

i.e,  \text{Hypotenuse side}^2=\text{sum of the square of two side}

Given a triangle with side lengths 6, 10, and 8.

If we square all the given sides, we get;

6^2 = 36,

8^2 = 64

10^2=100

It can be seen that the sum of 36 and 64 is 100

⇒6^2+8^2 = 10^2

which satisfies the Pythagorean theorem.

⇒ The triangle is right-angled with the side lengths 6 units and 8  units forming the right angle and the side length 10 units  being the hypotenuse.

Therefore, her answer is incorrect, she should have added 6^2 and 8^2 and compared that to 10^2
