Answer:

No solution

Step-by-step explanation:

So we have the equation:

$|x+5|+20=4$

First, subtract 20 from both sides:

$|x+5|=-16$

Now, we can stop. Recall that absolute value will always <em>always</em> give a positive answer.

Since this equals -16, this means that there is no solution.

And we're done!

Suppose a farm has pens for raising insects. A pen is shaped as a rectangle that measures x meters wide and 2x meters long and h

Ludmilka [50]

Answer:

1.2 meters.

Step-by-step explanation:

Length of pen = 2x meters

width of pen = x meters

shape of pen is rectangular

we know that area of rectangle is given by length * width

Thus, area of the pen is x*2x = $2x^2$

It is also given that area of pen is 2.8 square meters.

Equating numerical value of area with area in terms of x, we have

$2x^2 = 2.88\\=> x^2 = 2.88/2\\=> x^2 = 1.44\\=> x = 1.2$

Thus value of x is 1.2 meters.

Which relation is a function?

sashaice [31]

Answer:

Step-by-step explanation:

B. for it to be a proper function, it must pass the vertical line test (meaning, if you were to fill a continuous line between each of the dots, and then drew a string vertical line down at any point along the function, that vertical line cannot intersect with the function line more than once.

A, would fail the vertical line test, C< and D would also fail, as a vertical line would intersect/cross the function line more than once.

Determine the value of x

Black_prince [1.1K]

Answer:

144

Step-by-step explanation:

Using the corresponding angles theorem, we can find that the angles inside the parallelogram are equal to $\frac{x}{4}$ , $\frac{x}{4}$ , x, and x.

We also know that all parallelograms have 360 degrees in them.

Using this information, we can say that,

$\frac{x}{4} +\frac{x}{4} +x+x=360$

From here, we can solve for x.

2.5x = 360

x = 144
