Answer:

x = -1/2

Step-by-step explanation:

4(x + 3) = 9x + 16 + 3x

Distribute the 4

4x +12 = 9x+16+3x

Combine like terms

4x+12 = 12x+16

Subtract 4x

4x-4x+12 = 12x-4x+16

12 = 8x+16

Subtract 16

12-16 = 8x+16-16

-4 =8x

Divide by 8

-4/8 =8x/8

-1/2 =x

A student sees a newspaper ad for an apartment that has 1330 square feet (ft2 ) of floor space. how many square meters of area a
kkurt [141]

We know 1 meter = 3.28084 feet

So 1 square meter = 3.28084 × 3.28084 square feet.

Now to convert from square feet to square meters, we need to divide by 3.28084 × 3.28084.

The area given in the news paper advertisement is 1330 square feet.

So to convert to square meters we divide by 3.28084 × 3.28084

We get

1330 square feet = \frac{1330}{(3.28084)^{2} }  =123.56

Hence 1330 square feet of area is equal to 123.56 square meters.
