Answer:
Step-by-step explanation:
x2 - 6x = - 25
Rearrange the equation and let it be equal to 0
x2 - 6x +25 = 0
Using the Almighty formula
x =( -(-6) + √9)/2 or (-(-6) - √9)/2
x =4.5 or-1.5
x = 4.5
Answer:
the answer is -13.64 i just took the test and it right promise.
Step-by-step explanation:
mark me as brainliest pls its right
Multiply the numerator and denominator of the first question by 2 in order for both of the denominators to be the same.
1*2=2
3*2=6
Now that the denominators are the same, we can simply add the numerators and simplify if possible.
(2/6)+(1/6)= (3/6)
(3/6)= (1/2)
Final answer: 1/2
