What is the value of the expression 3 (5to the 3rd power) + 4t to the 2nd power when s = 5 and t = 3?

  411

Step-by-step explanation:

Put the values where the variables are and do the arithmetic.

  3s³ +4t² = 3(5³) +4(3²)

  = 3(125) +4(9) = 375 +36 = 411

answer: are you

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
