Answer:

12.5 un^2

Step-by-step explanation:

The formula for area of a trapezoid is (a+b)/2 *h

a and b are the shorter and longer bases respectively. H is height, you have both.

Simply plug it into the equation and find your answer.

(2.5+7.5)/2 *2.5 = 5*2.5 which is equal to 12.5. Add units.

I don’t understand this

Oxana [17]

You have to multiply whats outside the parenthesis with everything that is inside, so

$x^{-3}y^0.(x^2-3x^5y^4)$

$x^{-3}y^0.x^2-x^{-3}y^0.3x^5y^4$

Multiplication of same bases we sum the exponents

$x^{-3+2}y^0-3x^{-3+5}y^{0+4}$

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

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

Alternative B.
