Answer:Just Multiply both sides by LCM of the denominators of the fractions. It works for all equations.

Step-by-step explanation:The best way to solve a quadratic equation that contains a fraction. An example is 1/2x^2 - 2x = 3/2.

I multiply both sides by a number that gets rid of the denominators of all the fractions. E.g.,

Multiply your example by 2 on both sides:

x^2 – 4x = 3

x^2 – 4x – 3 = 0

Using Quadratic Formula:

x = (4 ± √(16–4(1)(–3)))/(2(1))

x = 2 ± √(4–(1)(–3))

x = 2 ± √(7)

A recipe requires 3/4 cups of water targa has a measuring cup that is marked only in ounce but she knows that 8 ounces is equiva

bulgar [2K]

Answer:

6 ounces of water

Step-by-step explanation:

In this question, we are asked to calculate the amount in ounce that would be added to the recipe.

From the question, we can see that the recipe requires 3/4 cups of water.

From the question also, we can also see that one cup equals 8 ounces.

Now to know the amount of water that is to be added, what we need to do is to simply multiply the fraction of water in the recipe by 8 ounces

This is equal to 3/4 * 8 = 6 ounces

Hence, she needs to add a total of 6 ounces of water to the recipe

The lengths of the

Dmitrij [34]

Answer:

$S_{\Delta ABC}$ = 4· $S_{\Delta EDC}$

Step-by-step explanation:

From the midpoint theorem, which states that the line that a line drawn such that it joins the midpoints of two sides of a triangle, is parallel to the third side of the triangle and is equal to half the length of the third side

Therefore, the lengths of the sides of ΔDEF, drawn by joining the midpoints of ΔABC is equal to half the length of and parallel to the corresponding side of ΔABC

We therefore, have that the corresponding sides of ΔABC and ΔDEF have a common ratio and a pair of sides in each triangle form same angles, therefore;

ΔDEF is similar to ΔABC by Side, Side, Side SSS similarity.

The length of the perimeter of ΔABC, $S_{\Delta ABC}$ = 2 × The length of the perimeter of triangle ΔEDC, $S_{\Delta EDC}$

$S_{\Delta ABC}$ = 2 × $S_{\Delta EDC}$

∴ $S_{\Delta ABC}$ ≠ 4 × $S_{\Delta EDC}$

The statement which is incorrect is therefore;

$S_{\Delta ABC}$ = 4 × $S_{\Delta EDC}$ .
