mel-nik [20]3 years ago

Step-by-step explanation:

let's simply do the multiplications and then compare with the original.

(x-m)² + n

right ?

or is it

{(x - m)}^{2 + n}

let's go for the first.

x² - 2mx + m² + n = x² - 3x

-2mx + m² + n = -3x

fun there we see two things :

-2m = -3

m = 3/2

and

m² + n = 0

(3/2)² = -n

9/4 = -n

n = -9/4

so our transformed expression looks like

(x - 3/2)² - 9/4

LOTS OF POINTS ANSWER ASA P , painter is painting a rectangular wall that measures 25.1 ft by 18.5 ft. Each gallon can of paint
svlad2 [7]

Answer:

1.548 gallons

Step-by-step explanation:

Length of the rectangular wall = 25.1 ft.

Width of the rectangular wall = 18.5 ft.

Area of the rectangular wall = length * width = 25.1 * 18.5

= 464.35 square feet

300 square feet wall can be painted using 1 gallon of paint.

=> 1 square feet wall can be painted using \[\frac{1}{300}\] gallon of paint.

=> 464.35 square feet wall can be painted using \[\frac{1}{300} * 464.35\] gallon of paint.

= 1.548 gallons of paint
