(5x-4y)^2
(5x-4y)(5x-4y)

Multiply each term in one bracket in turn by the terms in the other bracket

(5x)(5x) = 25x^2
(5x)(-4y)=-20xy
(-4y)(5x)=-20xy
(-4y)(-4y)=16y^2

Put them together we have
25x^2-20xy-20xy-16y^2
25x^2-40xy-16y^2

Hi 6 6 h h 13 13 Find the missing height. h = h=h, equals units The parallelogram shown below has an area of 72 7272 units 2 2 s
Yakvenalex [24]

Answer:

Height=12 Units

Step-by-step explanation:

Given a parallelogram with base b, and a perpendicular height, h. The area of the parallelogram is derived using the formula:

Area of a parallelogram=Base X Perpendicular Height

Given an area of 72 Units Squared.

Since I am not certain of the length of the base given:

If b=6

Area=bh

72=6h

Dividing both sides by 6

h=12 Units.

Height=12 Units

You can use the given formula to solve for the height,h of the parallelogram given any base b.
