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

A delivery truck is transporting boxes of two sizes large and small. The combined weight of a large box and a small box is 80 po

Liula [17]

Answer:

small=15 large=40

Step-by-step explanation:

x=large box

y=small box

55 = x + y

50x + 55y = 2825

50x + 55( 55 - x) = 2825

50x + 3025 - 55x = 2825

0 = 55x - 50 x + 2825 - 3025

0 = 5x - 200

200 = 5x

x=40

y = 15
