Answer:

Surface area of triangular prism = 528

Step-by-step explanation:

Surface area of triangular prism = (Base x Height) + 2 (length x side) + (length x base)

SA = bh + 2Ls + Lb

Putting given values : b = Y = 5 , h = 9 , s = x = 9 , L = z = 21

(5 x 9) + (2 x 21 x 9) + (21 x 5)

= 45 + 378 + 105

528

Which expression is equivalent to 2^6 x (2^2)^3?<br> O A 212<br> B. 215<br> O c. 236<br> OD 254

Semenov [28]

A. $\bold{\boxed{\green{2^{12}}}}$

Answer:

Solution given:

$2^6 x (2^2)^3$

we know that

product of power and power is added and power to power is multiplied for same base only.

I.E.

product of same base but different power: $a^b+a^c=a^(b+c)$

power to power : $(a^b)^c=a^(b*c)$

By using above property

$2^6+2^{2*3}$

$2^6+2^6$

$2^{[6+6]}=2^{12}$
