Answer:
4 chocolates
Step-by-step explanation:
Before Luke started eating, there were 8. This is 2/3 of what Sara had to start with, so she started with 12. That is 3/4 of what Mike started with, so he started with 16.
Jill left 4/5 of what she started with, so she must have started with 20. Jake ate 1/6 and left 5/6, so 20 is 5 times the number Jake ate.
Jake ate 4 chocolates.
___
Jill ate 4; Mike ate 4; Sara ate 4; and Luke ate 4.
Is the expansion of a Binomial Square . Perfect Square Trinomials have first and last terms that are positive perfect squares.
The answer is c.261 you add 13 and16 together then multiply that number by9
width = 13
length = 30
p=2l + 2w
86 = 2(2w+4) + 2w
86 = 4w + 8 + 2w
86= 6w + 8
78 = 6w
13 = w
86 = 2l + 2(13)
86 = 2l + 26
60 = 2l
30 = l
check your work.
l is 4 centimeters more than twice w
twice w = 26
plus 4 = 30
i hope you understand. ask questions if not
