Solve this equation for x: x^2+11x+28=0
lord [1]

Answer: x = -7 or x = -4

Step-by-step explanation: When an equation has a squared term in it

such as x² + 11x + 28 = 0, it's called a polynomial equation.

The rule for solving a polynomial equation

is to first set it equal to zero, then factor.

Since this equation is already set equal to zero,

our first step is to factor the left side of the equation.

To factor x² + 11x + 28, we need the factors

of 28 that add to 11 which are 7 and 4.

So we have (x + 7)(x + 4) = 0.

Whenever two terms are multiplied together to equal zero,

this means that either one or the other must equal zero.

So if (x + 7)(x + 4) = 0, then either x + 7 = 0 or x + 4 = 0.

Solving each equation from here, we get x = -7 or x = -4.

So our solution is {-7, -4}.

trapecia [35]

Answer:

3in up per foot across

Step-by-step explanation:

4ft across 12in height

6ft across 18in height

So for every 2ft it goes up 6” which is a ratio of 1ft:3in so the answer to the rate of change is 3in up per 1ft across

The number of mold cells doubles every 12 minutes. At this moment, there are x mold cells present on a piece of bread. Which of
lisabon 2012 [21]

Answer:

Step-by-step explanation:

Suppose that at time t_0 we have x mold cells. We are told that after 12 minutes the amount present is double. That is a t= t_0+12 we have 2x cells. Then, at t = t_0+24 we have (2x)*2 = 4x. We can continue as follows

t: t_0+36 we have (4x)*2 = 8x.

t: t_0+48 we have (8x)*2 = 16x

t: t_0+60 (one hour later) we have (16x)*2 = 32x.

So after one hour from now we have 32x cells.
