4 times a number is 32 less than the square of that number. Find the negative solution.
zvonat [6]

Answer:

<u>The negative solution is -4</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

x = a number

4x = x² - 32 (4 times a number is 32 less than the square of that number)

2. Let's solve for x and find the negative solution:

4x = x² - 32

-x² + 4x + 32 = 0

x² - 4x - 32 = 0 (Multiplying by - 1)

(x - 8) (x + 4) = 0

(x₁  - 8) = 0

(x₂ + 4) = 0

x₁ = 8

<u>x₂ = -4</u>

<u>The negative solution is -4</u>

Which numbers are perfect squares? Check all that apply.
Andrew [12]

A perfect square is a number made by squaring a whole number.

Since

  • 1^2=1;
  • 4^2=16;
  • 10^2=100,

numbers 1, 16, 100 are perfect squares. You cannot find such whole number n, that

  • 2=n^2;
  • 18=n^2;
  • 32=n^2;
  • 44=n^2;
  • 94=n^2,

therefore, numbers 2, 18, 32, 44, 94 are not perfect squares.

Answer: 1, 16, 100.

2/3x+4=3/5x-2? What’s the formula? Step by step? How do u do this?
Talja [164]

-90

Step-by-step explanation:

2/3x+4=3/5x-2

2/3x – 3/5x = -2 – 4

LCM for 5 & 3 is 15 so we can use it on the two fractions;

10/15x – 9/15x = 1/15 x

1/15x = -6

x = - 6 * 15

x = -90
