Answer:

30

Step-by-step explanation:

Find the trapezoid area.

A=1/2h(b1+b2)

A=1/2(12)(6+15)

A=1/2(12)(21)

A=6(21)

A=126

Find the square

A=s²

A=15²

a=225

Add them.

126+225=351

Divide

351÷12=29.25

Round to 30 because 29 not enough.

Which is equivalent to x^3 y^-7
PilotLPTM [1.2K]

For this case we must find an expression equivalent to:

x ^ 3 * y ^ {- 7}

By definition of power properties we have to meet:

a ^ {-1} = \frac {1} {a ^ 1} = \frac {1} {a}

Then, we can rewrite the expression as:

x ^ 3 * \frac {1} {y ^ 7} =\\\frac {x ^ 3} {y ^ 7}

Answer:

\frac {x ^ 3} {y ^ 7}
