If x = 4

x² + 2x = 24

Substitute x by its value

4² + 2(4)
16 + 8 = 24

We simply need to plug in x = 4 into x² + 2x

So plugging in x = 4, we get:

4² + 2(4)

Simplifying it, we get:

16 + 2(4)
16 + 8
24

When x = 4, x² + 2x will equal 24.

The coordinates of the vertices for rectangle ABCD are A (2,4), B (6,10), C (9,8) and D (5,2). What

sweet [91]

Answer:

D. $\sqrt{65}$

Step-by-step explanation:

The computation of the length of a diagonal (AC or BD) of the rectangle is shown below:

As we know that

The Diagonal length of AC is

$= (x_2 - x_1)^2 + (y_2 - y_1)^2\\\\= (9 -2)^2 + (8 - 4)^2\\\\= (7)^2 + (4)^2$

$= \sqrt{49 + 16}\\\\= \sqrt{65}$

Therefore correct option is D.

15x²y³z÷3xy² simplify

umka21 [38]

Answer:

$5xyz$

Step-by-step explanation:

$\frac{15x^2y^3z}{3xy^2}$

Step 1: Divide the numbers

$\frac{15}{3}=5\\\\=\frac{5x^2y^3z}{xy^2}$

Step 2: Simplify

$\frac{x^2}{x}\\\\= x\\\\=\frac{5xy^3z}{y^2}$

Step 3: Simplify

$\frac{y^3}{y^2} = y\\\\=5xyz$

Therefore, the simplified answer is $=5xyz$

A line segment is defined by which of the following statements?

kaheart [24]

The only given option that correctly defines a line segment is;

Option C; All points between and including two given points.

In geometry in mathematics, a line segment is defined as a part of a line that is bounded by two distinct end points.

Now, let us look at the options;

Option A; This is not correct because a line segment must have 2 distinct endpoints

Option B; This is not correct because a line segment is a part of a line and not a set of points.

Option C; This is correct because it tallies with our definition of line segment.

Option D; This is not correct because a line segment does not extend infinitely.
