6 0

Answer:

49

Step-by-step explanation:

To complete the square we use the formula:

c=(\frac{b}{2} )^{2}

So we can plug in 14 for b to find c.

c=(\frac{14}{2} )^{2}\\\\c=(7 )^{2}\\c=49

Now this equation can be factored into:

(x-7)^{2}

Marlena save $50 in an account earning 3.5% simple interest. How much would her account earn in 10 years?
katrin [286]

Answer: Her account would earn $17.5

Step-by-step explanation: The earning on a given amount with simple interest can be computed as follows;

Interest = PRT/100

Where P is the principal (initial amount), R is the rate of interest and T is the number of years. The formula now becomes,

Interest = (50 x 3.5 x 10)/100

Interest = 1750/100

Interest = 17.5

Therefore, in 10 years her account would have earned $17.5

The number of pages that Ana, Hillary, Roger, and Juan can read in a day is shown below:

For Ana

Ana read 15% of her 46-page book.

For Hillary

Hillary read 11% of her 72-page book.

= 11% × 72 pages

= 7.92 pages

For Roger

Roger read 12% of his 68-page book.

= 9.66 pages

The person who can read greatest number of pages in a day also means the person who read the highest number of pages in a day.

From the calculation above, that person in JUAN because she can read 9.66 pages of her book in one day.

5x − 3+ 2x = x + 7 + 6x
Masteriza [31]

Answer:

There isnt any solution.

Step-by-step explanation:

but these are the steps:

Step 1: Simplify both sides of the equation.

5x−3+2x=x+7+6x

5x+−3+2x=x+7+6x

(5x+2x)+(−3)=(x+6x)+(7)

7x+−3=7x+7

7x−3=7x+7

Step 2: Subtract 7x from both sides.

7x−3−7x=7x+7−7x

−3=7

Step 3: Add 3 to both sides.

−3+3=7+3

0=10
