Since a square has 4 equal sides, just do 19 + 19 + 19 + 19 which is 76. Or, 19 x 4, even though you add with permieter, it'll still work on a square. 

Hope I helped!

Square has 4 equal sides and the peremeter is adding all the sides together and so 19 + 19 + 19 + 19 = 76

kifflom [539]
A quadratic equation is one in which the highest exponent of x is 2.
7x^2+14x=0 is quadratic; the highest exponent is 2.
x³-3x²+1=0 is NOT quadratic.  The highest exponent of x is 3, not 2.
5x-7=0 is NOT quadratic.  The highest exponent of x is 1, not 2.
x²+3x-5=0 is quadratic; the highest exponent of x is 2.
x-5=9x+7 is NOT quadratic.  The highest exponent of x is 1, not 2.
x²-x=3x+7 is quadratic; the highest exponent of x is 2.

Need help to understand this question thank you :)

Complementary angles add up to equal 90 degrees. Knowing this, you can subtract 68 from 90. 90-68=22.

Hope this helps.
