Answer:
radical is sqrt we find 180 sqrt root
Step-by-step explanation:
first we write sqrt 180
sqrt 180 = ?
we can choose first two letters
18 are two letters
4^2 + 2 = 18
so first + third number choose
4 , 2 are number choose
4 + 2 sqrt (4+2-1)
6 sqrt 5
sqrt 180 = 6sqrt 5
Answer:
49a^2 - 126ab + 81 ^2
Step-by-step explanation:
Suitable identity = (a-b)(a-b) = a^2 - 2ab + b^2
So, to solve this.
(7a-9b)(7a-9b) = 49a^2 - 126ab + 81b^2
Hope this helps

Answer:
$4 78 cents
Step-by-step explanation:
If home improvement store advertises 60 square feet of flooring for $287.00 ($80 installation fee inclusive), to get the price per square feet of the flooring cost, we will use the expression;
60 sq.ft = $287
1 sq. ft = $x
Cross multiply
60x = 287
Divide both sides by 60
60x/60 = 287/60
x = 4.783
x ≈ 4.78 (to the nearest hundredth)
Hence the price per square feet of the flooring is $4.78 or $4 78 cents
<em>Note that $80 was not added to $287 because we are told that this price ($287) already includes the installation fee.</em>
