Answer:
x = 65
Step-by-step explanation:
x = √(25×(25+144))
x = √(25×169)
x = 5×13
x = 65

Answer:
A. The solutions are .
B. The factored form of the quadratic expression
Step-by-step explanation:
A. To find the solutions to the quadratic equation you must:
The solutions are:
B. Two expressions are equivalent to each other if they represent the same value no matter which values we choose for the variables.
To factor :
First, multiply the constant in the polynomial by where is equal to -1.
Since both terms are perfect squares, factor using the difference of squares formula
4, then 13. Since the 4 is positive it doesn’t need to change, and 13 is negative therefore it will be positive
(1,2/3)(-1,-1)
slope = (-1 - 2/3) / (-1-1) = (-3/3 - 2/3) / -2 = (-5/3)/-2 = -5/3 * -1/2 = 5/6
y = mx + b
slope(m) = 5/6
(-1,-1)...x = -1 and y = -1
now we sub
-1 = 5/6(-1) + b
-1 = -5/6 + b
-1 + 5/6 = b
-6/6 + 5/6 = b
-1/6 = b
y = 5/6x - 1/6 <=== ur equation
