Answer:

$\boxed{\bold{ab+9a-6}}$

Step-by-step explanation:

Remove parenthesis: (a) = a

$\bold{2ab+9a-4-\left(ab+2\right)}$

$\bold{-\left(ab+2\right): \ -ab-2}$

$\bold{2ab+9a-4-ab-2}$

Simplify $\bold{2ab+9a-4-ab-2}$

$\bold{ab+9a-6}$

mr Goodwill [35]

What you do is add up the coins in two piles
1. all the coins added up
2.coins that are more than 10 cents (or equal)
take number 2 and put that in the numerator (top spot on a fraction)
and take number 1 and put it on the denominator (bottom spot on a fraction)
then simplify it if needed.
50/224 is the raw data simplify it for the real answer
25/112 is the simplest you can do so there's your answer. hope this helped :)

Answer:

x=1

Carlos is tiling a kitchen cluster that is 12 feed by 3 feed. The counter has a rectangular hole 3 feet by 2 feet cut in ir for

Taya2010 [7]

Answer:

The area of the counter that Carlos will wall tile is $30 ft^{2}$

Step-by-step explanation:

to solve this, we will calculate the area of the counter and the area of the rectangular hole that Carlos would have to leave out for the sink, and then subtract them to get the area that will be tiled.

Total area of the rectangular counter = length X breadth = $12 \times 3 = 36ft^{2}$

area of the rectangular cut out for the sink = length X breadth = $3 \times 2 = 6 ft^{2}$

Surface area that Carlos is meant to tile = $36ft^{2}- 6 ft^{2} = 30ft^{2}$

Hence,the area of the counter that Carlos will wall tile is $30 ft^{2}$
