Type the correct answer in the box. Use numerals instead of words. Consider this expression.
(a^3 – 7 squared) + |b|
When a = 2 and 5 =
-4, the value of the expression is

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400

dwe

step-by-step explanation:

ewd

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.
