Which expression is equivalent to (x3 · x2)5? x10

marysya [2.9K]

<h2> The given expression is equivalent to $x^{5}$ .</h2>

Step-by-step explanation:

The given expression is

$x^3.x^2$

To write the given expression is equivalent = ?

The given expression is

$x^3.x^2$

We know that,

The exponential identity,

$a^{m}.a^{n}=a^{m+n}$

= $x^{3+2}$

= $x^{5}$

∴ The given expression is equivalent = $x^{5}$

Thus, the given expression is equivalent to $x^{5}$ .

Firefighters used a ladder 50 feet high to reach a window that was 30 feet above the ground. From the same point on the ground,

deff fn [24]

First since 2 of the options ask for the width of BM lets solve for it using the Pythagorean theorem for both sides of point L:
a² + b² = c²
30² + b² = 50²
b² = 50² - 30²
b² = 1600
b = 40 Line BL = 40 ft
Since the ladder is 50 feet it is the same length on the other side as well
a² + b² = c²
40² + b² = 50²
b² = 50² - 40²
b² = 900
b = 30 line LM is 30 ft
SO line lm + line bl = 30 + 40 = 70 ft
A is true because ^
B isn't true because as we solved for earlier, BL is 40
C is true because line LM is in fact 30 ft as we solved for
D is not true because as we said earlier BM is 70
E is true because the same ladder was used on both sides of the street

Use elimination to solve the system of equations. 2x+y=4 and -4x-2y=8

goldfiish [28.3K]

Answer: No solution

Step-by-step explanation:

To use elimination method, we need to choose a variable to eliminate. Let's eliminate x. To eliminate x, the x coefficient in both equations must be the same, regardless of the sign. To do so, let's multiply the first equation by 2.

(2x+y=4)2

-4x-2y=8

-------------------------------------------------------------------------------------------------------------

4x+2y=8

-4x-2y=8

Let's add both equations together.

0=8

-------------------------------------------------------------------------------------------------------------

Now that we got this far, we can see that something is wrong. This normally doesn't happen. If you notice, the second equation is the first equation but multiplied by 2. Instead, let's rewrite each equation.

2x+y=4 [subtract both sides by 2x]

y=-2x+4

-4x-2y=8 [add both sides by 4x]

-2y=4x+8 [divide both sides by -2]

y=-2x-4

-------------------------------------------------------------------------------------------------------------

If you analyze both equations, you will see that they are parallel lines. We know this because the slopes are the same, but different y-intercept. from our knowledge of parallel lines, they NEVER touch or cross. This means there would be no solution at all.
