A father complained that his son's allowance of $5 per week was too much. The son replied, "Okay, Dad. How about this?
You give me a penny for the first day of the month, 2 cents for
the next, 4 cents for the next, 8 cents for the next, and so on for
every day of the month." The father readily consented. Who was
the more clever? What would the son's allowance be on day 31?
what is the name of the equation i need to use and what is the answer

here the number -5 is all of the following except a rational number.

step-by-step explanation:

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
