this is formula. You can also refer to the attachment
Answer:
Step-by-step explanation:
(a + b) (a² - ab + b) = a*(a² - ab + b) + b(a² - ab + b)
= a*a² - a*ab +a*b + b*a² - b*ab + b*b
= a³ - a²b + ab + a²b -ab² + b²
= a³ - a²b + a²b + ab - a²b + b²
= a³ + ab - a²b + b²

how many yards
carpeting is needed to cover a 60 feet length room and 40 feet width
Answers
Answer:
[tex]266[/tex] [tex]\frac{2}{3}[/tex] [tex]yards[/tex]
Step-by-step explanation:
1. Approach
First, convert the dimensions of the room from feet to yards. Remember, the conversion rate between feet and yards is, [tex]3feet=1yard[/tex]. Next, find the area of the room by multiplying the length by the width.
2. Convert the unit of measurement
The measurement unit is given in feet, one must convert it into yards. The conversion rate between yards and feet is, [tex]3feet=1yard[/tex].
[tex]60feet=20yards\\\\40feet=13\frac{1}{3}yards[/tex]
3. Find the area of the room
Now multiply the length by the width to find the area of the room.
[tex]20yards*13\frac{1}{3}yrads\\\\= 20 * \frac{40}{3}\\\\=\frac{800}{3}\\\\= 266\frac{2}{3}_{.}yards^{2}[/tex]

7. Find the value of x 8. find the value of y
Answers
Answer:
x = 27.8
y = 35
Step-by-step explanation:
∡D ≅ ∡A, therefore:
65 = 2y - 5
70 = 2y
y = 35
EF ≅ BC, therefore:
2x + y = 90.6
2x + 35 = 90.6
2x = 55.6
x = 27.8
