Since they are similar, that means they are proportionally the same.
So KL is similar to PN
JL is similar to PM

So,
You need to find how much bigger is the second triangle from first.
It is proportionally scaled up.

KL/JL = PN/ PM

You basically put in order of triangles. Left triangle on left side of equal sign and right triangle on right side of equal sign. You put in denominator the similar sides and numerator the similar sides (the side that is similar to the side of the other triangle)

5/6 = PN / 9
Cross-multiply
PN * 6 = 5*9
6PN = 45
PN =45/6

PN =7.5

Quentin has 18 unit cubes. how many different rectangular prisms can be build if he uses unit cubes

kvv77 [185]

18 = 2·3·3

So possibles prisms are:

2×3×3

1×2×9

1×6×3

1×1×18

Therefore Quentin can make 4 different rectangular prism with 18 unit cubes.

What are the real and complex solutions of the polynomial equation x^4+3x^2-4

Lyrx [107]

Answer: (D) -1,1,-2i,2i

Explanation:

$x^4+3x^2-4 = 0\\x^2 \rightarrow z\\z^2 + 3z -4 = 0 \\z_1 = -4\\z_2 = 1\\x_{1,2} = \pm\sqrt{-4}=\pm 2 i\\x_{3,4} = \pm 1$

Factor 1/3 out of 1/3p-2/3 please answer this! Easy 20 points!

Tju [1.3M]

Answer:

$\frac{1}{3} (\frac{1}{p} - 2)$

Step-by-step explanation:

Given the equation = $\frac{1}{3p} - \frac{2}{3}$

Required: To factor out 1/3;

$\frac{1}{3p} - \frac{2}{3}$

1/3 is common to both sides;

So, 1/3 is a common factor

$\frac{1}{3} (\frac{1}{p} - 2)$

To solve for the value of p;

$\frac{1}{3} (\frac{1}{p} - 2)$ = 0

$\frac{1}{p} - 2 = 0$

$\frac{1}{p} = 2$

$1 = 2p$

$p = \frac{1}{2}$
