Four students were asked to write an expression which has terms that have a greatest common factor of ab. The expressions provided by the students are shown below.
Michelle
16a+ 3b
Naomi
18abc-13abc
Olivia
20ab-14abc
Peyton
15abc+ 14 ab
Which student wrote the correct expression?
O Michelle
O Naomi
Olivia
O Peyton

i think da answer is

d.square root of 3

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .

a) is $10.34

b) is 6 toppings
