P/2=4+p/3>> p=24

24/2=4+24/3
12=4+8
12=12 p=24

$\frac{p}{2} + \frac{3}{4} = \frac{p}{3}\\\\12(\frac{p}{2} + \frac{3}{4}) = 12( \frac{p}{3})\\\\6p + 9 = 4p\\9 = -2p\\\\p=-\frac{9}{2}\\\\p = -4.5$

A square has side length of 9 in. If the area is doubled, what happens to the side length?

Alika [10]

Answer:

The side length is multiplied by $\sqrt{2}$

Step-by-step explanation:

we know that

The area of the original square is equal to

$A=9^{2}=81\ in^{2}$

If the area is doubled

then

The area of the larger square is

$A1=(2)81=162\ in^{2}$

Remember that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z ----> the scale factor

x ----> the area of the larger square

y ---> the area of the original square

$z^{2}=\frac{x}{y}$

we have

$x=162\ in\^{2}$

$y=81\ in\^{2}$

$z^{2}=\frac{162}{81}$

$z^{2}=2$

$z=\sqrt{2}$ ------> scale factor

therefore

The side length is multiplied by $\sqrt{2}$

Find the absolute value of the complex number 5 - 4i.

Damm [24]

I answered a similar question for someone else. The absolute value of a complex number is called the modulus. This represents the DISTANCE to the origin from the point on the imaginary + real plane.
the real horizontal distance is 5 and the imaginary vertical distance is in this case 4 (from -4i) the distance is 4. So to figure out this just use the Pythagorean theorem.
5^2 + (4)^2 = c^2
25 +16 = c^2
c^2 = 41c = 6.4 So option D.

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

a is a leg
b is another leg
c is the hypotenuse

Step-by-step explanation:

Step 1: Define

Leg a = 8

Leg b = 4

Hypotenuse c = x

Step 2: Solve for x

Substitute in variables [Pythagorean Theorem]: 8² + 4² = x²
Evaluate exponents: 64 + 16 = x²
Add: 80 = x²
[Equality Property] Square root both sides: √80 = x
Rewrite: x = √80
Simplify: x = 4√5
