M1= 5 , M2=1

Explanation:

12-3m-4-5/m=0
8-3m-5/m=0
(8-3m-5/m=0) * m
8m-3m^2-5=0
8m-3m^2=5
m(8-3m)=5
m1=5
m2=> (8-3m)=5
3m=3
m2= 1

Answer:

m=1\\m=\frac{5}{3}

Step-by-step explanation:

12 - 3m = 4 + \frac{5}{m}

8=\frac{5}{m} +3m

Multiply the whole thing by m

8m = 5 +3m^{2}

3m^{2} -8m + 5 = 0

(3m^{2} -3m) + (-5m +5)

3m(m-1)-5(m-1)=0

3m-5=1\\m-1=0

m=1\\m=\frac{5}{3}

An open box is to be made from a rectangular piece of tin by cutting 3-inch squares out of the corners and folding up the sides.
slava [35]

Answer:

Width of the Rectangular Tin=8 inch

Length of the Rectangular Tin= 16 inch

Step-by-step explanation:

Let the Width of the Rectangle=W

The length of the piece of tin is twice the width, Length = 2W

Since Squares of 3 inch are cut from all four corners of the rectangle

Length of the box = 2W-(3+3)=(2W-6) inches

Breadth of the Box = W-(3+3)=(W-6) inches

Height = 3 inches

Volume of the box = 60 cubic inches

Now, Volume of a cuboid=lbh

3(2W-6)(W-6)=60

Divide both sides by 3

(2W-6)(W-6)=20

Expanding the brackets

(2W-6)(W-6)=20\\2W^2-12W-6W+36=20\\2W^2-18W+36-20=0\\2W^2-18W+16=0

Factorizing

2W^2-16W-2W+16=0\\2W(W-8)-2(W-8)=0\\(W-8)(2W-2)=0\\W-8=0 ,  2W-2=0\\W=8,  1

Since the Width cannot be less than 6,

Width of the Rectangular Tin=8 inch

Length= 2 X 8 = 16 inch
