When 5 is subtracted from the square of a number, the result is 4 times the number. Find the negative solution. PLEASE HELP FAST!! LIKE ASAP LOL

x = -1

Step-by-step explanation:

First, we can translate this statement to the equation

Subtracting 4x from both sides gives us a quadratic equation:

From here, we can factor the expression on the right to give us the equation's two solutions. The factored form will look like

We need a + b = -4 and ab = -5, and picking a = 1 and b = -5 do the job there. Our expression factors then to (x + 1)(x - 5), giving us the equation

And the solutions x = -1 and x = 5. Since we're only looking for the negative solution, x = -1 is the one we want.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
