In a survey of 290 newspaper, 181 of them read the daily times, 142 read the Guardian, 117 read punch and each read at least one of the three papers if 75 read the daily times and the Guardian, 50 read the daily times and punch and 54 read the guardian and the punch a) draw the venn diagram to illustrate the illustration
b) how many user read all paper
c) exactly two of the paper
d) exactly one of the paper
e) The guardian only​

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
