Answer: 10x-6

Step-by-step explanation:

we know that perimeter P is 2L+2W

2L= 2(3x+2)=6x+4

2W=2(2x-5)=4x-10

P=6x+4+4x-10=10x-6

Answer:

$455.84

Step-by-step explanation:

find area of the two halves of the circle and the rectangle

area of circle= $\pi r^{2}$

where r= 2 ft

therefore

$\pi (2)^{2}\\=12.56 ft^{2}$

area of rectangle= $w*l$

where w= 4ft and l= 5ft

therefore

$(4)(5) \\=20 ft^{2}$

add areas together

$12.566 + 20 \\=32.56 ft^{2}$

it costs $14 per square foot and there are 32.566 square feet, so multiply

$14 * 32.56 \\= $455.84$

Value of r is -4

Step-by-step explanation:

We are given points (-1,-6) and (0,r) on line and slope of line is -2. We need to find value of r.

Using slope formula when two points are given:

$Slope=\frac{y_2-y_1}{x_2-x_1}$

Where $x_1=-1,\,\,y_1=-6,\,\,x_2=0,\,\,y_2=r$

Putting values:

$2=\frac{r-(-6)}{0-(-1)} \\2=\frac{r+6}{0+1} \\2=\frac{r+6}{1} \\2=r+6$

Adding -6 on both sides:

$2-6=r\\-4=r$

So, Value of r is -4
