I think this is right
a = 8
b = 8
c = 5
d = 9
Answer:
x=√65 and x=-√65
Step-by-step explanation:
Givn the expression 2x^2 - 9 = 121
Add 9 to both sides
2x^2 - 9 + 9 = 121 + 9
2x^2 = 130
Divide both sides b 2
2x^2/2 = 130/2
x^2 = 65
x = ±√65
x=√65 and x=-√65
Answer:
Step-by-step explanation:
the answer would be x=0 because if this problem is proportional 5 x 4 = 20
and 0 x 4 =0
The answer to the question is 33-6=27 so x=27
