Find the area of the regular polygon 7 in

nata0808 [166]

Ummmm that’s a triangle but I guess I’ll solve for both 7x7= 49/2= 24.5 triangle. Polygon is different but I guess if the perimeter and line to the center is both 7 okay 7x5= 35x7= 245/2= 122.5 cause triangle is wxL /2 and polygon is AxP/2 soooo I hope this helped

aleksandrvk [35]

Assignment: $\bold{Factor \ 4u^2-28u+49}$

<><><><><>

Answer: $\boxed{\bold{\left(2u-7\right)^2}}$

<><><><><>

Explanation: $\downarrow\downarrow\downarrow$

<><><><><>

[ Step One ] Rewrite $\bold{4u^2-28u+49}$

$\bold{\left(2u\right)^2-2\cdot \:2u\cdot \:7+7^2}$

[ Step Two ] Apply perfect square formula

Note: Perfect Square Formula: $\bold{\left(a-b\right)^2=a^2-2ab+b^2}$

$\bold{a=2u,\:b=7}$

$\bold{\left(2u-7\right)^2}$
