(2x + 3y)^2– (2x – 3y)^2

Mathematics
1 answer:
Korolek [52]2 years ago
6 0

Hi,

(2x + 3y)² - (2x - 3y)²

  • (a + b)² = a² + 2ab + b²
  • (a - b)² = a² - 2ab + b²

= [(2x)² + 2x*3y + (3y)²] - [(2x)² - 2x*3y + (3y)²]

= (4x² + 6xy + 9y²) - (4x² - 6xy + 9y²)

= 4x² + 6xy + 9y² - 4x² + 6xy - 9y²

= 12xy

I hope it helped ✅(◠‿◕)

Lisa has 3 quarts of milk. Sanjay has 12 pints of milk. Who has more?
Ira Lisetskai [31]

Sanjay, because quarts are twice as big as pints.

Step-by-step explanation:

Given

Milk quantity for Lisa = 3 quarts

Milk quantity for Sanjay = 12 pints

We have to convert both quantities in same unit so that we can compare both quantities.

We know that there are two pints in a quart.

So,

Lisa will have:

3*2 = 6 pints of milk

Hence,

Sanjay, because quarts are twice as big as pints.

PLEASE HELP!!!!!!!!
Kitty [74]

32 cm long

15 cm wide

6 cm tall

 

The surface area is the sum of the area of all six sides

 

Two sides are 32 x 15

Two sides are 15 x 6

Two sides are 6 x 32

 

32 x 15 = 480

15 x 6 = 90

6 x 32 = 192

 

Surface area = 2(480) + 2(90) + 2(192) = 960 + 180 + 384 = 1524 cm2
