Similar triangles have their corresponding sides in the same ratio. So we have

x/8 = 9/5

cross multiply
5*x = 8 * 9

5x = 72

now divide both sides by 5:-

x = 72/5 = 14.4 Answer

Find the product of the expression:<br> (5p^3) (-1m^8p^2)

Rainbow [258]

Answer:

We conclude that:

$\left(5p^3\right)\:\left(-1m^8p^2\right)=-5p^5m^8$

Step-by-step explanation:

Given the expression

$\left(5p^3\right)\:\left(-1m^8p^2\right)$

Apply the rule:

$a\left(-b\right)=-ab$

so the expression becomes

$\left(5p^3\right)\left(-1\cdot \:m^8p^2\right)=-5p^3\cdot \:1\cdot \:m^8p^2$

Apply the rule:

$a^b\cdot \:a^c=a^{b+c}$

so the expression becomes

$=-5p^{3+2}\cdot \:1\cdot \:m^8$ ∵ $p^3p^2=p^{3+2}$

$=-5p^5\cdot \:1\cdot \:m^8$

$=-5p^5m^8$

Therefore, we conclude that:

$\left(5p^3\right)\:\left(-1m^8p^2\right)=-5p^5m^8$
