State the factoring rule for special cases (a+b)2=

if you mean (a+b)^2 then the rule is..

(a+b)^2=

a^2+2ab+b^2

Step-by-step explanation:

its simply a property of math or a formula and if u want proof this works try it with any two terms like this for example:

(a+b)^2=

(2+7x)^2=

Subsitute.

a^2+2ab+b^2

2^2+2*2*7x+2x^2

so.. 4+28x+4x^2

or 2x^2+28x+4 is your answer :)

and if you solve this using the

(2+7x)(2+7x) looping method thingy

then you will see that you get the same answer of

2x^2+28x+4.

this proves that the formula works.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

wait nvm i know the correct answer now its 100%   81 square feet
