Answer:

$3584

Step-by-step explanation:

- because its a rectangle, the area of the floor is length*width, so 16*14 = 224 square feet

- one square foot is $16, so 224 sqaure feet are 224*16

= 3584

Answer:

$3584

Step-by-step explanation:

To find square feet, multiply the length measurement in feet by the width measurement in feet.

16 x 14 = 224

Now, find how much it costs, there is 224 square feet in total so since it's 16 dollar for every square feet.

224 x 16 = 3584

QUESTION 1a.

We want to add

( - 2 {x}^{2}  - 4x + 13) + (12 {x}^{2}  + 2x - 25)

We group similar terms to get

- 2 {x}^{2}  + 12 {x}^{2}- 4x + 2x   - 25 + 13

Simplify:

- 10{x}^{2} - 2x  -12

QUESTION 1b.

The given function is:

(7x^2+4x-26)-(-7x^2-3x+15)

Expand the parenthesis to obtain,

7x^2+4x-26 + 7x^2 + 3x - 15

Group similar terms,

7x^2+7 {x}^{2}  + 4x + 3x-26  - 15

Simplify:

14{x}^{2}  + 7x-41

QUESTION 2

The given function is

f(n)=n^2-6n-16

The zeros of this function is given by;

n^2-6n-16 = 0

Split the middle term.

n^2-8n + 2n-16 = 0

Factor;

n(n - 8) + 2(n - 8) = 0

(n - 8)(n + 2) = 0

n - 8 = 0 \: or \: n + 2 = 0

n  = 8 \: or \: n =  - 2

(a)It takes 51
never [62]

a) Given :

51 pounds of seed  can be planted in = 9 acre field.

Per pound of seed = \frac{9 \ acre}{51 \ pounds \ of \ seed}

We can convert 9/51 in simplest fraction by dividing top and bottom by 3.

We get

\frac{9/3}{51/3}=\frac{3}{17}

<h3>Therefore, 3/17 of an acrs can be planted per pound of seed.</h3>

b) $10 amount = 16 pounds of sugar.

$1 amount = 16/10 = 1.6 pounds of sugar.

<h3>Therefore, 1.6 pounds of sugar she got per dollar.</h3>

wlad13 [49]

Answer:

The answer is A.

Step-by-step explanation:

Because it takes 5730 years for half of a sample of carbon-14 atoms to decay. It says that 50% of the carbon atoms have decayed so that means that 5730 years have elapsed for that fossil.

Hope this helps!
