PLEASE HELP ANSWER ASAP

lana66690 [7]

Answer:

x = 20

Step-by-step explanation:

Use Pythagorean Theorem to solve for x:

a^2 + b^2 = c^2

Plug in given values if a = 12, b = 16, and c = x (x is hypotenuse)

12^2 + 16^2 = x^2

(12*12) + (16*16) = x^2

144 + 256 = x^2

400 = x^2

Take square root of both sides to solve for x

sqrt(400) = sqrt(x^2)

20 = x or x = 20

(8x3 - 30x + 21) / (4x -6)

abruzzese [7]

Answer:

$\frac{ {8x}^{3} - 30x + 21 }{2(2x - 3)}$

Step-by-step explanation:

1) Factor out the common terms 2.

$\frac{8x^{3} - 30x + 21}{2(2x - 3)}$

Therefor, the answer is 8x³ - 30x + 21 / 2 ( 2x - 3 ).

14) ¿Cuántos cubos de 1 cm por lado caben dentro de otro cubo que mide por lado 2cm?

vlabodo [156]

Answer: 8

Step-by-step explanation:

Ok, el volumen de un cubo de lado L es:

V = L^3

Entonces, el volumen de un cubo de 1cm por lado es:

V = (1cm)^3 = 1cm^3

Y el volumen de cubo cuyos lados miden 2cm es:

V' = (2cm)^3 = 8cm^3.

Ahora, la cantidad de cubos chicos que van a entrar en el cubo grande es igual al cociente entre sus volúmenes:

V'/V = (8cm^3)/(1cm^3) = 8

Entran 8 cubos de 1 cm por lado en un cubo de 2cm por lado.
