Mathematics

Alexxx [7]3 years ago
7 0

Pi is commonly written as 3.14 even though it has an infinite decimal point value. 3pi multiplied by d (which d equaling 12pi) is our expression. Pi = 3.14. 3 x 3.14 = 9.42. 12 x 3.14 = 37.68. The expression is now 9.42 multiplied by 37.68. 9.42 x 37.68 = 353.8456.

Please help with a math problem :/ Please show steps...<br><br> x^2 -13x = -36
Marianna [84]
X^2 -  13 x = -36 
add 36 to both sides

x^2 - 13x +36 = 0
figure out the factor
(x-4)(x-9) = 0
so (x-4) or (x-9) equals 0
so solution is
x-4=0 add 4 to both sides and get x = 4
x-9=0 add 9 to both sides and get x=9
x={ 4, 9}
