Hello there!

(2x - 3)(x² + 4x - 6)

Start by using the distributive property

=(2x)(x²) + (2x)(4x) + (2x)(-6) + (-3)(x²) + (-3)(4x) + (-3)(-6)

= 2x³ + 8x² - 12x - 3x² - 12x + 18

= 2x³ + 5x² - 24x + 18

As always, it is my pleasure to help students like you!

24-4x=2x<br> show your work, will mark brainliest

vladimir2022 [97]

Answer:

x=4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

24−4x=2x

24+−4x=2x

−4x+24=2x

Step 2: Subtract 2x from both sides.

−4x+24−2x=2x−2x

−6x+24=0

Step 3: Subtract 24 from both sides.

−6x+24−24=0−24

−6x=−24

Step 4: Divide both sides by -6.

−6x /−6 = −24 /−6

x=4

Find AC <br> What Is The Equation To AC?

In-s [12.5K]

<u>Given</u>:

Given that ABC is a right triangle.

The length of AB is 7 units.

The measure of ∠A is 65°

We need to determine the length of AC

<u>Length of AC:</u>

The length of AC can be determined using the trigonometric ratio.

Thus, we have;

$cos \ \theta=\frac{adj}{hyp}$

Where the value of $\theta$ is 65° and the side adjacent to the angle is AC and the side hypotenuse to the angle is AB.

Substituting the values, we have;

$cos \ 65^{\circ}=\frac{AC}{AB}$

Substituting AB = 7, we have;

$cos \ 65^{\circ}=\frac{AC}{7}$

Multiplying both sides by 7, we get;

$cos \ 65^{\circ} \times 7=AC$

$0.423 \times 7=AC$

$2.961=AC$

Rounding off to the nearest hundredth, we get;

$2.96=AC$

Thus, the length of AC is 2.96 units.
