Question

me ayudann porfavorrrr​

Answer 1

a) x/4 = 2 × 108

x = 216 × 4 = 864

b) 2(x+1) = 56/2

2x + 2 = 28 _ x = 28 - 2 / 2 _ x = 26/2 = 13

c) 3(x²) = 1 + 74

3(x²) = 75 _ x² = 75/3 _ x² = 25 _ x = ²/25 = 5

d) ³/ x × 2 +10 = 14

³/ x × 2 = 14 - 10 _ ³/x × 2 = 4 _ x = 4³/2 _ 64/2 = 32

Answer 2

Respuesta:

a) es igual a 864, b) es igual a 13, c) es igual a {+5 y -5}, d) es igual a 32

Explicación paso a paso:

a)

$\frac{a}{4}=2*108\\ a=216*4\\a=864$

b)

$2*(b+1)=\frac{56}{2}\\b+1=\frac{28}{2}\\ b=14-1\\b=13$

c)

$3*c^{2}=74+1\\c^{2}=75/3\\c=\sqrt{25}\\c=\left{{+}\atop{-}}\right.5$

d)

$\sqrt[3]{2*d}+10=14\\\sqrt[3]{2*d}=4\\2*d=4^{3} \\2*d=64\\d=32$
