So, this is too vague but I'll solve for both quadratic formula and find the discriminant.
Quadratic formula: <span>x=<span>5+<span><span><span>√35 OR</span><span> </span></span>x</span></span></span>=<span>5−<span>√<span>35
Finding the discriminant: 141</span></span></span>
If A is your age:
400 - 2A = 244
2A = 400 - 244
2A = 156
A = 78
Answer:
a = -2
Step-by-step explanation:
-(5a+6)=2(3a+8)
-5a -6 = 2*3a +2*8
-5a -6 = 6a +16
-5a -6a = 16+6
-11a = 22
a= -22/11
a = -2
2.8a^2=55
a^2=55/2.8
a= square root of 55/2.8
