|
Equation type: conditional |
One answer 2x = 10 … X = 5 |
|
|
Equation type: contradictions |
No answers will work. False. X+1=x+2.… Can't happen. |
|
|
Equation type: identities |
All real numbers work. x+2 = 2+x
|
|
|
Commutative prop |
Order changes. a+b=b+a ONLY works for adding and multiplying. |
|
|
Associative property |
Parenthesis () relocate but order stays the same. (a+b)+c=a+(b+c) ONLY addition and multiplying |
|
|
Identity |
Identity: results in original # a*1= a |
|
|
Inverse property |
Inverse: multiplying by the reciprocal of a number a * ¹/a = 1 |
|
|
Distributive prop |
Adding same coefficients. -6r +13r = -7r |
|
|
Area of a rectangle |
A= l*w |
|
|
Perimeter of a rectangle |
P=2l+2w Or all sides added together |
|
|
Circumference |
C=πd or 2πr |
|
|
Area of a square |
A=s² |
|
|
Area of a circle |
A=πr² |
|
|
Area of a Parallelogram |
A=b•h |
|
|
Area of a triangle |
A= ½•b•h |
|
|
Volume of a box |
V=lwh |
|
|
Angles that add to 90° |
Complimentary angles. 2 angles! a+b=90 |
|
|
