Answer:

The answer would be x = 6 , − 6

Step-by-step explanation:

x 2 = 36

Take the square root of both sides of the equation to eliminate the exponent on the left side.

x = ± √ 36

The complete solution is the result of both the positive and negative portions of the solution.

ki77a [65]

Answer:

Step-by-step explanation:

let x be the side length of the small square

x² + (x + 3)² = 89

x² + (x² + 6x + 9) = 89

2x² + 6x - 80 = 0

x² + 3x - 40 = 0

(x + 8)(x - 5) = 0

so x = -8 or x = 5

A negative length does not make sense

small square side 5 inch

5 + 3 = 8

large square side 8 inch

The value of (-15/23)+(+30/-46) is ---------.

amm1812

$\frac{ - 15}{23} + \frac{30}{ - 46} \\ = \frac{ - 15}{23} + \frac{(2) \times (15)}{(2) \times ( - 23)} \\ = \frac{ - 15}{23} + \frac{15}{ - 23} \\ = \frac{ - 15}{23} - \frac{15}{23} \\ = \frac{ -3 0}{23} \\ = - 1.3$

PLEASE HELP

zhuklara [117]

Beck add like terms so you get
4x^2 -4x-15
lucy factor our negative so you left with -4x^2 +5x -10 +8x^2 -9x -5
simplify 4x^2 -4x -15
therefore both students answers simplify to 4x^2 -4x -15
