Unit 1: test

2πr or πd

P=2(a+b)

P=2(l+w)

P=4s

P=s1+s2+s3+s4

A=lw

A=s²

A=bh

A=1/2bh

A=πr²

length x width x height

V=πr²h

S= 2lw+2lh+2wh

S= 2pirh+ 2pir^2

expressions that have the same value

any quantity is equal to itself

if a=b, then b=a

If a=b and b=c, then a=c

a + 0 = a

a + (-a) = 0

a x 1 = a

Two numbers with a product of 1

Number order can be changed without changing the answer

The way in which numbers are grouped does not change their sum or product

If a = b, then a can be substituted for b in any equation or expression

a(b + c) = ab + ac

a portion of a function where the y-values are greater than 0 for all x-values

A portion of a function where the y-values are less than 0 for all x-values
