3x^2-4=7x standard form in quadratic ?
Natalka [10]
<span>3x^2 - 4 = 7x is the standard form. To get standard form into quadratic you must have one side of the equation equal zero. The easiest way to so is subtracting 7x on both sides of the equation.

What is the value of x?<br>Enter your answer in the box<br>​
Ber [7]

Answer:

x = 8

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

The square on the hypotenuse is equal to the sum of the squares on the other two sides, that is

x² + 6² = 10²

x² + 36 = 100 ( subtract 36 from both sides )

x² = 64 ( take the square root of both sides )

x = \sqrt{64} = 8

4.) Together Alice &amp; Mindy have saved $490 for a trip this summer.
Trava [24]

Answer:

Mindy=191

Amy=299

Step-by-step explanation:

first you want to divide $490 in half to see what each person has. Thats 245 and since Amy has $54 more, you minus 54 from 245 to get 191. So while Mindy has 191, Amy has 299
