Area of rectangle = Length × Width

Length - (3x+2)
Width - (4x+10)

Area of rectangle = (3x+2) × (4x+10)

Area of rectangle = 3x(4x+10) + 2(4x+10)

Area of rectangle = 12x² + 30x + 8x + 20

Area of rectangle = 12x² + 38x + 20

Hence , the area of rectangle is 12x² + 38x + 20 units

Answer:

Step-by-step explanation:

Area of rectangle = length * width

= (3x + 2)(4x + 10)

= 3x *(4x + 10) + 2*(4x + 10)

= 3x *4x + 3x *10 + 2*4x + 2*10

= 12x² + <u>30x + 8x</u> + 20 {Combine like terms}

= 12x² + 38x + 20

You place the spring vertically with one end on the floor. You then drop a book of mass 1.50 kg onto it from a height of 0.900 m

Alex777 [14]

Answer:

The value of the maximum distance the spring will be compressed

x = 0.143 m= 14.3 cm

Step-by-step explanation:

Given data

Mass m = 1.5 kg

h = 0.9 m

k = 1500 $\frac{N}{m}$

Since the book is released from a height h = 0.9 m above the top of the spring. so the total distance

y = h + x

Now in that case for the spring

$mg y= \frac{1}{2} k x^{2}$

$mg(h +x) = \frac{1}{2} k x^{2}$

By rearranging the above equation we get

$k x^{2} - 2mgx - 2mg h = 0$

Put all the values in above equation we get

$1500x^{2} - 29.43 x - 26.48 = 0$

By solving the above equation we get

x = 0.143 m= 14.3 cm

This is the value of the maximum distance the spring will be compressed.
