2x^2 + 16x + 50 = 0
divide through by 2:-
x^2 + 8x + 25 = 0
(x + 4)^2 - 16 + 25 = 0
(x + 4)^2 = -9
x+4 = 3i or -3i
x = -4 + 3i , -4 - 3i
Answer: x=18, y=30
explanation: bc i’m right
Answer:
A = 10
Step-by-step explanation:
Use formula: c = sqrt of a^2 + b^2
1) Put in known numbers:
26 = sqrt of a^2 + 24^2
But instead of adding you would subtract and rearrange the formula bc you already have C:
2) Solve:
A = sqrt of 26^2 - 24^2
A = sqrt of 676 - 576
A = sqrt of 100
A = 10
Sqrt: square root
Therefore, out answer… I hope this helps! Best of Luck! (\^ v ^/)
Answer:

Answer:
2 1/4
Step-by-step explanation:
- 5 1/4 - ( - 7 1/2)
Subtracting a negative is like adding
- 5 1/4 + 7 1/2
Get a common denominator of 4
-5 1/4 + 7 2/4
Subtract
7 2/4 - 5 1/4
2 1/4
