Answer:

Step-by-step explanation:

Use FOIL method

(x + 3)(x - 5) = x*x + x *(-5) + 3*x + 3*(-5)

= x² - 5x +3x - 15 {add like terms}

= x² - 2x -15

3/4×-18=1/4×-4 help me slove

WINSTONCH [101]

3/4 x -18 = 1/4 x -4

subtract 1/4 x from each side

3/4 x -1/4 x -18 = 1/4 x- 1/4 x -4

2/4 x - 18 = -4

add 18 to each side

1/2 x -18 + 18 = -4 + 18

1/2 x =14

multiply by 2 on each side

2* 1/2 x = 14 * 2

x =28

The diameter of a semicircle is 6 miles. What is the semicircle's perimeter?

koban [17]

Answer:

$15.42mi$

Step-by-step explanation:

Use the formula for a semicircle's perimeter.

$P=\frac{1}{2}\pi *d+d$

Plug in 6 for d.

$P=\frac{1}{2}\pi*6+6$

Let's use 3.14 for $\pi$ , just to make it easier, but of course, if it states to round it to something else, just plug in that many values for $\pi$ .

$P=\frac{1}{2}(3.14)*6+6 \\ \\ P=1.57*6+6 \\ \\ P=9.42+6 \\ \\ P=15.42$

Answer:

1/2 ornament in an hour

Step-by-step explanation:

Given

$Orna\ ments = 2$

$Time = 4$

Required

Determine the ornaments per hour

This question implies that we calculate the unit rate.

$Unit\ Rate = \frac{Orna\ ments}{Time}$

Substitute values for Time and number of ornaments

$Unit\ Rate = \frac{2}{4}$

$Unit\ Rate = \frac{1}{2}$

<em>This implies that Constance can decorate 1/2 ornaments in an hour</em>
