Help please Can you clear fractions in an equation by multiplying each side by a common denominator other than the LCD? Give an

Katena32 [7]

Yes here is an example:_

x/4 + 5/6 = 2

The LCD of 4 and 6 is 12 but we can also multiply through by 24 to clear the fractions:-

x/4 * 24 + 5/6 * 24 = 2 + 24

6x + 20 = 40

This will give us the same result if we multiplied through by 12.

In triangle ABC, AB = 11 cm, BC = 9 cm and CA = 10 cm. Find the area of triangle ABC.

max2010maxim [7]

Answer:

Area = 42.43 square cm

Step-by-step explanation:

Using Heron's Formula :

$Area = \sqrt{s\times (s-a) \times (s-b) \times(s -c)} \ , \ where \ s \ =\ \frac{a+ b+ c}{2}$

Find Area :

$s = \frac{11 + 9 + 10 }{2} = \frac{30}{2} = 15$

$Area = \sqrt{15 \times ( 15 - 11 ) \times { (15 - 9 ) \times ( 15 -10)}\\\\$

$= \sqrt{15 \times 4 \times 6 \times 5}\\\\=\sqrt{1800}$

$= 42 . 43 \ cm^2$

How do you solve the equation y-3=-¼(x+3)

likoan [24]

Because you have two variables and only one equation, you can only solve for approximate answers, and not complete, absolute answers.

<h3>You can simplify this equation to x = -4y + 12</h3>

y - 3 = -1/4(x + 3)

Distributive property.

y - 3 = -1/4x - 3/4

Multiply all terms by 4.

4y - 12 = -x

Multiply all terms by -1

-4y + 12 = x
