Parentheses first. So (2+3) = 5. Then (5)×2 = 10. 22 is already over 10, and you're adding to that so that would make it false

What is the area of a rectangle with a width of 4 2/3 meters and a length of 2 1/6 meters?

inessss [21]

Answer:

Area = 10 1/9 meters squared

Step-by-step explanation:

mixed number to improper fraction:

4 2/3 meters = 14/3 meters

2 1/6 meters = 13/6 meters

Area = length times width:

Area = (14/3) x (13/6)

= 182/18

Simplify fraction:

182/18 = 91/9

improper fraction to mixed number:

91/9 = 10 1/9 meters

AREA = 10 1/9 meters

Expand.<br> Your answer should be a polynomial in standard form.<br> (3c + 2)(c^2-6c-4)

evablogger [386]

Answer:

After expanding the polynomial $(3c + 2)(c^2-6c-4)$ we get $3c^3-16c^2-24c-8$

Step-by-step explanation:

We need to expand the polynomial $(3c + 2)(c^2-6c-4)$

Multiply the terms:

$(3c + 2)(c^2-6c-4)\\=3c(c^2-6c-4)+2(c^2-6c-4)\\=3c^3-18c^2-12c+2c^2-12c-8\\=3c^3-18c^2+2c^2-12c-12c-8\\=3c^3-16c^2-24c-8$

So, after expanding the polynomial $(3c + 2)(c^2-6c-4)$ we get $3c^3-16c^2-24c-8$
