Answer:

The "2" in the second term is a coefficient.

Step-by-step explanation:

$3x^2-11(2y+1)+4$

In the given expression ,

3 in the first term is a the coefficient of x^2

11 is the factor of second term

4 is the constant in third term

2 is the coefficient of y

So, The "2" in the second term is a coefficient.

Rectangular swimming pool has a perimeter of (6x-6) feet and a width of x. find the length

Dvinal [7]

The first thing you should know for this case is that the perimeter of a rectangle is defined as:
P = 2L + 2W
Where
L = length
W = Wide
We then have to clear the length:
L = (P-2W) / 2
Substituting the values
L = ((6x-6) -2x) / 2
Rewriting:
L = ((3x-3) -x)
L = 2x-3
Answer:
the length is
2x-3

The length of a standard jewel case is 3 cm more than its width. The area of the rectangular top of the case is 304 cm squared.

valentina_108 [34]

Answer:

width = 16 cm

length = 19 cm

Step-by-step explanation:

Let the width be x cm.

Given that length is 3 cm more than width then

length = x+3 cm

area of rectangle = 304 square cm. -----1

area of rectangle is given by

area =length * width

substituting from equation 1 and length and width in terms of x we have

304 = x(x+3)

$=> 304 = x^2+3x\\\\=> 304 -304= x^2+3x -304\\=> 0= x^2+3x -304\\=> x^2+3x -304 = 0\\=> x^2+19x - 16x -304 = 0\\=> x(x+19 ) -16(x+19) = 0\\=> (x-16) (x+19 )= 0\\x-16 = 0 \ or \ x+19 = 0\\ x= 16 \or \ x = -19$

As length cannot be negative hence x = 16

Thus width = x = 16 cm

length = x+3 = 16+3 = 19 cm
