3) 95 Students

Step-by-step explanation:

1) As can be known from the question

Then, draw the venn diagram according to the known conditions.

2) 60 + 75 - 20 = 115 { Draw a venn diagram to calculate }

115 + 285 = 400

3) 60 - 20 + 75 - 20 = 95 ( Draw a venn diagram to calculate }

Find the sum and product of the roots. 2x^2 + 6x - 8 = 0
netineya [11]
Suppose you can factorize:

ax^2+bx+c=a(x-r_1)(x-r_2)

Then by expanding the right side, you have

ax^2+bx+c=a(x^2-(r_1+r_2)x+r_1r_2)=ax^2-a(r_1+r_2)x+ar_1r_2

which means in this case, you have to have

\begin{cases}6=-2(r_1+r_2)\\-8=2r_1r_2\end{cases}\implies\begin{cases}r_1+r_2=-3\\r_1r_2=-4\end{cases}

Answer:

5a. 4w+24≤100

5b. Dimensions=31ft x 19 ft

      Area = 589ft²

Step-by-step explanation:

l=w+12

p=2l+2w

p=2(w+12)+2w

p=2w+24+2w

p=4w+24

The farmer has 100ft of fencing, so maximum that the perimeter (p) can be is 100, meaning (4w+24) has to be less than or equal to 100:

4w+24≤100

For the largest possible perimeter, all 100 of fencing will be used, so allow 100 to be equal to 4w+24)

100=4w+24

4w=76

w=19ft

l=w+12

l=19+12

l=31ft

The dimensions are 31ft x 19ft.

Area=lw

=31*19

=589ft²
