$\bf \cfrac{comedie}{action}\qquad 8:7\qquad \cfrac{8}{7}\qquad \qquad \cfrac{32}{a}=\cfrac{8}{7}\implies \cfrac{32\cdot 7}{8}=\stackrel{action}{a}$

Find the surface area of the square pyramid 8mm 6mm

bija089 [108]

Answer:

136 mm²

Step-by-step explanation:

$A=a^{2} +2a\sqrt{\frac{a^{2} }{4} } +h^{2}$

$A=6^{2} +2(6)\sqrt{\frac{6^{2} }{4} } +8^{2}$

$A=36 +12\sqrt{\frac{36 }{4} } +64$

$A=36 +12\sqrt{9 } +64$

$A=36 +12(3)+64$

$A=36 +36+64$

A = 136

Write the expression as a square of a monomial 121a^6

Nutka1998 [239]

<span>The square root of 121 is 11. The square toot of a^6 is a^3. Therefore 121a^6 can be expressed as (11a^3)^2, and 11a^3 is a monomial since it is a single term with nothing added or subtracted to it or from it. So 121a^6 as a squared monomial is (11a^3)^2.</span>
