Cadesia has $42.70, which is 175% of the amount that Alisha has. How much money, in dollars, does Alisha have?

without knowing the value of "x" in the specific question, its not possible to answer the value of the ×.

Answer:

-3, - 7

Step-by-step explanation:

x² + 10x + 14 = -7

x² + 10 x + 21 = 0

Now let's complete the square.

(x + 5)² - 25 + 21 = 0

(x+5)² - 4 = 0

(x+5)² = 4

x + 5 = ± root 4 = ± 2

x = +2-5 or -2-5 = -3 or -7

The values of x that meet the equation x2 + 10x + 14 = -7 are x = -3 and x = -7.

The given equation is: x2 + 10x + 14 = -7.

Transfer the constant term to the opposite side of the equation:

x2 + 10x + 14 + 7 = 0.

Combine comparable terms to simplify the equation: x2 + 10x + 21 = 0.

Complete the square by rewriting the equation with a constant term. To do so, square half of the coefficient of x (which is 10):

Half of ten equals five, and five squared equals twenty-five. Insert 25 into the equation:

x^2 + 10x + 25 + 21 - 25 = 0

Rearrange the terms as follows:

(x2 + 10x + 25) + (21 - 25) = 0.

Reduce the first set of brackets to a perfect square trinomial:

[tex](x + 5)^2 + (-4) = 0[/tex]

Reduce the number of constant terms:

[tex](x + 5)^2 - 4 = 0[/tex]

To find x, take the square root of both sides:

[tex]√((x + 5)^2 - 4) = √0[/tex]

Determine x: x + 5 = 4

To simplify even further, we have: x + 5 = 2

Solve for x separately:

x = -5 + 2 = -3 x = -5 - 2 = -7

As a result, the answers to the equation x2 + 10x + 14 = -7 are x = -3 and x = -7.
