we are given with a triangle with the sides 6 ft, 21 ft, 23 ft. although it follows the rule of triangles that state that no side of the triangle exceeds the sum of the lengths of two other sides, this does not follow Pythagorean theorem: 23^2-21^2 = 88 which is not equal to 6^2 or 36. This is not a right triangle, hence. Hope this helps!

What is the sum of the first 75 even numbers starting with 2? Enter your answer in the box.
vova2212 [387]

Answer:

5700

Step-by-step explanation:

step 1 Address the formula, input parameters & values.

Input parameters & values:

The number series 2, 4, 6, 8, 10, 12, .  .  .  .  , 150.

The first term a = 2

The common difference d = 2

Total number of terms n = 75

step 2 apply the input parameter values in the AP formula

Sum = n/2 x (a + Tn)

= 75/2 x (2 + 150)

= (75 x 152)/ 2

= 11400/2

2 + 4 + 6 + 8 + 10 + 12 + .  .  .  .   + 150 = 5700

Therefore, 5700 is the sum of first 75 even numbers.
