Solve for x. NEED ANSWER ASAP TYY SO MUCH IN ADVANCE
Serjik [45]

Answer:

x = 10√3

Step-by-step explanation:

Because of the right angles, we can use Pythagoras

30² - x² = y²  (a) Largest triangle

y² - 20² = h² (b) Medium triangle

substitute y² from (a) into (b)

30² - x² - 20² = h²

500 - x² = h²  (d)

x² - h² = (30 - 20)² (c) smallest triangle

substitute h² from (d) into (c)

x² - (500 - x²) = 100

2x² = 600

x² = 300

x = 10√3

Use a graphing calculator to sketch the graph of the quadratic equation, and then give the coordinates for the x-
Umnica [9.8K]

Given:

The quadratic equation is

y=6x^2-15x+6

To find:

The x-intercepts of the given equation.

Solution:

We have,

y=6x^2-15x+6

Splitting the middle term, we get

y=6x^2-12x-3x+6

y=6x(x-2)-3(x-2)

y=(x-2)(6x-3)

For x-intercepts, y=0.

(x-2)(6x-3)=0

Using zero product property, we get

x-2=0\text{ and }6x-3=0

x=2\text{ and }6x=3

x=2\text{ and }x=\dfrac{3}{6}

x=2\text{ and }x=0.5

So, the x-intercepts are (0.5,0) and (2,0).

Therefore, the correct option is a.
