Your friend says that 14.5% is equivalent to the decimal 14.5. explain why your friend is incorrect by comparing the fractional

adoni [48]

14.5% = 0.145 = 145/1000

14.5 = 14500/1000

So 14.5% is a hundredth the size of 14.5, so they are not equal and the friend is incorrect.

Determine the area of the shaded region (grey) in the quadratic form.

NeX [460]

Answer:

The area of shaded region is: $13x^2+6x-15$

Step-by-step explanation:

We can see in the diagram that

$Length\ of\ gray\ rectangle = l_g = 3x+5\\Width\ of\ gray\ rectangle = w_g = 4x-3$

The area of rectangle is given by:

Area = Length * width

Now for gray rectangle

$A_g = l_g * w_g\\= (3x+5)(4x-3)\\= 3x(4x-3)+5(4x-3)\\= 12x^2-9x+20x-15\\=12x^2+11x-15$

For White Rectangle:

$Length = l = 5-x\\Width = w = x\\A_w = l * w\\A_w = (5-x)(x)\\= 5x-x^2$

Now,

The area of shaded region will be calculated by subtracting the area of white triangle from the gray triangle.

$A_s = A_g - A_w\\= (12x^2+11x-15) - (5x-x^2)\\=12x^2+11x-15-5x+x^2\\=12x^2+x^2+11x-5x-15\\=13x^2+6x-15$

Hence,

The area of shaded region is: $13x^2+6x-15$
