The problem is in the picture :)
frozen [14]

Answer:

Last option: 4

Step-by-step explanation:

The quadratic equation simplified: x^2-4x=-\frac{7}{2} has the form:

ax^2+bx=c

In this case, you can identify that "a", "b" and "c" are:

a=1\\b=-4\\c=-\frac{7}{2}

To solve this quadratic equation  by completing the square, Carlos should add (\frac{b}{2})^2 to both sides of the equation. This is:

(\frac{-4}{2})^2=(-2)^2=4

Then:

x^2-4x+4=-\frac{7}{2}+4

Therefore you can observe that the number he should add to both sides of the equation is: 4

PLEASE HELP!!! I WILL GIVE BRAINLIEST!!! Explain how to use estimation to help find the product of two decimals. Give an example
san4es73 [151]
You can use estimation to find the product of two decimals by rounding both the decimal’s so the nearest tenth or tens place (depending on how long it is) and then multiplying the decimals.

for example, if you had 4.6 and 8.9, you have to round the 4.6 and 8.9. you round the 4.6 up to 5 because the 6 bumps the 4 up to 5) and then round 8.9 to 9 (because the 9 bumps the 8 up to 8.) then, multiply 5 and 9 and you get 45!
