Answer:

x = 8.17

Step-by-step explanation:

We will be using pythagoras theorem:

$a^{2} + b^{2} = c^{2}$

=> $4.25^{2} + x^{2} = 9.21^{2}$

=> $x^{2}$ = 84.8241 - 18.0625 = 66.7616

=> x = $\sqrt{66.7616}$ = 8.17077719.. = 8.17 (3 s.f)

Factor. Explain.<br> 24x³y²-4x²y+84x^4

Elan Coil [88]

Answer:

$\boxed{\bold{4x^2\left(6xy^2-y+21x^2\right)}}$

Step By Step Explanation:

Apply Exponent Rule $\bold{\:a^{b+c}=a^ba^c}$

$\bold{x^4=x^2x^2,\:x^3y^2=x^2x}$

$\bold{24x^2x-4x^2y+84x^2x^2}$

Rewrite 84: $\bold{21\cdot \:4}$

Rewrite 24: $\bold{6\cdot \:4}$

$\bold{6\cdot \:4x^2x-4x^2y+21\cdot \:4x^2x^2}$

Factor Out Common Term $\bold{4x^2}$

$\bold{4x^2\left(6xy^2-y+21x^2\right)}$

➤ $\boxed{\bold{Mordancy}}$
