The number which could be added to both sides of the equation to complete the square is; -2.25.

<h3>Which number could be added to both sides of this quadratic equation to complete the square?</h3>

The quadratic equations give in the task content is; 1=x²-3x. Hence, to express the equation by completing the square method; we have;

1 - 2.25 = (x -3/2)² - 2.25

Hence, the number which should be added to both sides of the equation is; -2.25.

Answer:

16

Step-by-step explanation:

To start off this problem, we are given that the line AB is equal to the line CD. In addition to that, we are given that the line EF equally intersects line AB and line CD. This provides us proof that angle AGH is equivalent to angle DHG. From this information, we can solve this problem relatively easily.

Lets work with this equation:

80 = 5x

Next, divide 80 by 5.

\frac{80}{5} =x

16 = x

This means that x is equal to 16.

What is the value of x in the equation: 5(6x - 4) = 20 + 4(3 + x)?
satela [25.4K]

Answer:

x = 2

Step-by-step explanation:

5 ( 6x - 4 ) = 20 + 4 ( 3 + x )

30x - 20 = 20 + 12 + 4x

30x - 20 = 32 + 4x

26x = 52

x = 2

Can someone please help
sveta [45]
Some of the problems are in scientific notation, which if you don't know how to do, I will try to explain, when you see for example 1 x 10^3, what it is saying is basically 1 x 10 x 10 x 10 so in that case 1,000, simple trick is to look at what ever number is in the top right, then add that many zeroes. So this is most likely supposed to be a division problem. if you need more help message me.
