Answer:

n = 36

Step-by-step explanation:

The opposite sides of a parallelogram are congruent , that is

AB = DC , substitute values

$\frac{2}{3}$ n - 5 = $\frac{1}{3}$ n + 7 ( multiply through by 3 to clear the fractions )

2n - 15 = n + 21 ( subtract n from both sides )

n - 15 = 21 ( add 15 to both sides )

n = 36

Answer:

n = 36

Step-by-step explanation:

AB = DC because it is a parallelogram

so:

2/3n - 5= 1/3n + 7

simplify by adding 5 to each side of the equation:

2/3n = 1/3n + 12

simplify by subtracting 1/3n from both sides of the equation:

1/3n = 12

multiply both sides of the equation by 3:

n = 36

What is the volume of a box with a width 2 1/2 inches, length 1 3/4 inches, and height 3 1/4 inches?

enot [183]

Answer:

The volume of the box is 41.21 inches cube.

Step-by-step explanation:

Given,

Width of the box $2\frac{1}{2}$ inches

$=\frac{5}{2}$ inches

Length of the box $1\frac{3}{4}$ inches

$=\frac{7}{4}$ inches

Height of the box $3\frac{1}{4}$ inches

$= \frac{13}{4}$ inches

The box is in cuboid form.

The volume of cuboid is given by (length × breadth × height ).

So,

volume of the box is $( \frac{5}{2}$ × $\frac{7}{4}$ × $\frac{13}{4}$ $)$

= $( \frac{455}{32} )$

$= 14.21$ inches cube

The volume of the box is 41.21 inches cube.

Consider the equation: x^2+10x+22=13 Need help asap!!!! this is due in a hour!

klio [65]

Answer:

(x + 5)^2 = (5 - 3)^2

Step-by-step explanation:

Given the equation;

x^2 + 10x + 22 = 13

We have;

x^2 + 10x = 13 - 22

x^2 + 10x = -9

Adding half of 10 to both sides and completing the square as usual, we have;

(x + 5)^2 = 5^2 + (-9)

(x + 5)^2 = (5 - 3)^2
