If the<em> price is $180 per square foot</em>, the price of the lot will be $3,240,000

To calculate Xavier cost, we need to first calculate the area of the lot (trapezium)

Area of the trapzium = 1/2(a+b)h

h is the height of the trapezium
a and b are the sides

Area of the trapezium = 1/2(175+185)*100

Area of the trapezium = 1/2(360)*100

Area of the trapezium = 18000 square foot.

If the<em> price is $180 per square foot</em>, the price of the lot will be 18000 * 180 = $3,240,000

Answer:

errr polynomials ahaha

so basically we can multiply the power outside of the parantheses with the exponents on the inside:

$-3x^{2*4} y^{1*4}$

this will give us:

-3x^8y^4

we also unfortunately, have to use the power on the coefficient -3 as well and we cant just MULTIPLY -3 by 4, we are going to have to multiply -3 with -3 4 TIMES(anytime we see a coefficient we MUST multiply the coefficient by itself according to the number outside of the parantheses)

so:

-3*-3*-3*-3=81

final expression

$81x^{8}y^{4}$
