Answer:

11x^(2) - 3

Step-by-step explanation:

Remove the parentheses: (a)=a

=5x^2-7x+10+7x^2-11-x^2+7x-2

Group the like terms:

=5x^2+7x^2-x^2-7x+7x+10-11-2

Add the similar elements : 5x^2+7x^2-x^2=11x^2

=11x^2-7x+7x+10-11-2

Continue to add similar elements: -7x+7x=0

=11x^2+10-11-2

Then add or subtract the numbers:  10-11-2=-3

<u>FINAL ANSWER</u>:= <em>11x^(2)-3</em>

The wildflowers at a national park have been decreasing in numbers. There were 1200 wildflowers in the first year that the park
Andreas93 [3]

Answer:

Step-by-step explanation:

We have total 1200 wildflowers in first year that is first term a  is 1200

We have to find sigma notation  showing the infinite growth of the wildflowers.

wildflowers=\sum_{i=1}^{\infty }1200(\frac{1}{4})^{i-1}

Formula for infinite sum of GP is S_{\infty}=\frac{a}{1-r}

Here, a=1200,r=\frac{1}{4}

On substituting the values in the formula of sum we get:

S_{\infty}=\frac{1200}{1-\frac{1}{4}}

On simplification we get:

S_{\infty}=\frac{1200}{\frac{3}{4}}=1600

Therefore, total sum of wildflowers 1600.

Sally used all of the paint shown to make a certain tint of orange paint. How many pints of red paint should be mixed with 24 pi
ruslelena [56]

Answer:

18 pints

Step-by-step explanation:

As we can see, three pint of yellow paint was mixed with four pint of red paint. Let x represent the number of yellow paint and let y represent the number of red paint. Therefore, the ratio of the two paints is:

x/y = 3/4

x = (3/4)y

To calculate the number of red paints (x) that is needed to be mixed with 24 pints of yellow paint, we use the equation and substitute y as 24. Hence:

x =  (3/4)y

x =  (3/4) * 24

x = 18 pints
