Step-by-step explanation:
< i'll use this too represent angle
this is only presuming that this is a parallelogram and i also don't know what those numbers mean
< ACB = < CAD (alt <s of DA II CB) A
< ACD = < CAB (alt <s of DC II AB) A
AB is common S
therefore, ∆ADC is congruent to ∆CBA
if ∆ADC is congruent to ∆CBA
then < ADC = < CBA
Answer:
36.00
Step-by-step explanation:
Here is some pro tips, I take algebra 1, and I’m in middle school too.
x * x = x^2
If you see anything like (x + 5)(x - 5), solve using FOIL, (front, outer, inner, last), it’s basically the distributive property for four numbers and x’es.
Distributive property is a must know.
And also, if you are feeling nervous, remember, even if you fail the leap test, it doesn’t make you less of a intelligent, kind, and caring person.
Answer:
3
Step-by-step explanation:
its 3
Answer:
Not possible
Step-by-step explanation:
supposing both the roots as α and β and a,b and c are all positive real numbers.
Then α+β= -b/a which will be negative
⇒ α+β<0
and αβ= c/a , which will positive
⇒αβ>0
also, -b/a>0 and c/a<0
⇒b/a<0 and c/a<0 which is not possible because all a, b and c are positive real numbers.
hence, it is not possible that the quadratic equation ax²+bx+c=0 has a positive real solution if a,b and c are all positive real numbers
