____ [38]3 years ago

3 0

Answer:

$(x+3)(x+9)$

Step-by-step explanation:

We are given the expression $x^2+12x+27$

This means that we are looking for two numbers that would add together to give us 12 and multiply to give us 27.

The two numbers that fit this description are 3 and 9.

This means that the factored form of the expression would be

$(x+3)(x+9)$

Answer:

The dependent variable: the total cost

The independent variable: the amount of books

If the equation is y = 8x + 200

y would be the dependent variable and x would be the independent variable

I hope this helps.

In this diagram, bac~edf. if the area of bac= 6 in.², what is the area of edf? PLZ HELP PLZ PLZ PLZ

NemiM [27]

Answer:

2.7 in²

Step-by-step explanation:

Area of ∆BAC : ∆Area of EDF = BC² : EF² (based on the area of similar triangles theorem)

Thus:

$6 in^2 : x in^2 = (3 in)^2 : (2 in)^2$

$\frac{6}{x} = \frac{3^2}{2^2}$

$\frac{6}{x} = 2.25$

$\frac{6}{x}*x = 2.25*x$

$6 = 2.25x$

$\frac{6}{2.25} = \frac{2.25x}{2.25}$

$2.67 = x$

Area of ∆EDF = 2.7 in²

Rearrange the equation so u is the independent variable.<br><br> -12u + 13 = 8w - 3 <br><br> w = __

deff fn [24]

Answer: w = -3u/2 + 2

Step-by-step explanation:

-12u + 13 = 8w - 3

-12u + 13 + 3 = 8w -3 + 3

-12u + 16 = 8w

w = -3u/2 + 2
