Answer:

14(x +5)

Step-by-step explanation:

The denominator of the first expression is ...

2x+10 = 2(x +5)

The denominator of the second expression is ...

7x +35 = 7(x +5)

The least common denominator (LCD) is the product of the unique factors in these denominators:

2×7×(x +5)

= 14(x +5) . . . . least common denominator

= 14x +70

Answer:

Slope of the line DV = -1

Step-by-step explanation:

Let point D (-5, 1) be $(x_{1}, y_{1})$

Let point V (-1, -3) be $(x_{2}, y_{2})$

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

Plug in the appropriate values,

$m = \frac{-3-1}{-1-(-5)} = \frac{-4}{4} = -1$

slope equals -1

Given that the points (-1, 5) and (2, 1) are vertices of a rectangle with sides parallel to the axes, how much longer is the len

Norma-Jean [14]

Answer:

Correct choice is A

Step-by-step explanation:

Two vertices of the rectangle have coordinates A(-1, 5) and B(2, 1). If rectangle sides are parallel to the axes, then two remaining vertices have coordinates C(-1,1) and D(2,5) (see attached diagram for details).

Find the length and the width:

$AC=\sqrt{(-1-(-1))^2+(5-1)^2}=4\ units,\\ \\AD=\sqrt{(2-(-1))^2+(5-5)^2}=3\ units.$

Then the length is 1 unit longer than the width.

Patton's troops covered 48 miles in 4 hours. he then increased the speed by 8 miles an hour. if the total distance was 108 miles

masya89 [10]

48 miles/4hrs = 12 mph

Increased Speed 12 mph + 8mph = 20 mph

Distance left 108 miles - 48 miles = 60 miles

Time left 60 miles/20 mph = 3 hours
