Which expression is equivalent to (5^√3^2)^1/3 ?
kiruha [24]

Answer:

\frac{-177}{286}

Explanation:

Given,

\left(\frac{3}{11}\times\frac{5}{6}\right)-\left(\frac{9}{12}\times \frac{4}{3}\right)+\left(\frac{5}{13}\times \frac{6}{15}\right)

ft(\frac{5}{22}\right )-\left(\frac{36}{36}\right)+\left(\frac{2}{13}\right)

{5}{22}\right )-1+\left(\frac{2}{13}\right)

{5\times 13-286+2\times 22}{286}

{65-286+44}{286}

{109-286}{286}

{-177}{286}

Can someone please help me on this question? I don’t know how to solve it, it’s for geometry
Rom4ik [11]

Answer:

x = 28, y = 34

Step-by-step explanation:

70 + 4x - 2 = 180

110 = 4x - 2

112 = 4x

x = 28

(y + 9) + (y - 1) + 2(y - 4) = 136

4y = 136

y = 34
