How to solve (x+2)^3/4=27

Mathematics

\frac{(x + 2)^{3}}{4} = 27
4(\frac{(x + 2)^{3}}{4}) = 4(27) Multiply it by 4 on each side.
(x^{2} + 2)^{3} = 108 
\sqrt[3]{(x^{2} + 2)^{3}} = \sqrt[3]{108} Find the cube root of each.
x^{2} + 2 \approx 4.76
x^{2} \approx 2.76 Subtract 2 from each side.
\sqrt{x^{2}} \approx \sqrt{2.76} Find the square root of each.
x \approx \±2.76

If f(x) = <img src="https://tex.z-dn.net/?f=%5Cfrac%7Bx%2B3%7D%7B4%7D" id="TexFormula1" title="\frac{x+3}{4}" alt="\frac{x+3}{4}

Answer:

option (b) is correct

inverse of function  f(x)=\frac{x+3}{4} is 4x+3

Step-by-step explanation:

Given function f(x)=\frac{x+3}{4}

We have to find the inverse of given function.

Let f(x) = y then taking inverse both sides, we get

f^{-1}(y)=f^{-1}(f(x))\\\\\ f^{-1}(y)=x

Substitute , x  and f(x) in given equation, we get,

f(x)=\frac{x+3}{4} \Rightarrow \frac{(f^{-1}(y))+3}{4}

Now solve for (f^{-1}(y)) , we get,

(f^{-1}(y))+3=4y

(f^{-1}(y))=4y-3

Thus, inverse of function  f(x)=\frac{x+3}{4} is 4x+3

Thus, option (b) is correct.

Vedmedyk [2.9K]

Answer:

x = 52

Step-by-step explanation:

∡RQS = 180 - (90 + 34)

∡RQS = 56°

∡PQS + ∡RQS = 180°

∡PQS = x + 72

x + 72 + 56 = 180

x + 128 = 180

x = 52
