Write and solve an addition equation to find x.
perimeter = 48 ft
others= 20 & 12
equation= 20+12+x=48

20 + 12 + x = 48    / -20
12 + X = 48 - 20    / -12
X = 48 - 20 - 12
X = 28 - 12
X = 16

the image of (6, 9) under a dilation is (4, 6). the scale factor is

b. 2/3

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
