It would be C. It’s the most valuable answer to the equation. I did my caclucations
Answer:
- 0.7
Step-by-step explanation:
We are given the general quadratic formula, as " 
. " This can be represented by two separate formula's, which will come in handy when determining the positive and negative roots of the equation ( and here we need the negative root ):
1 ) 
,
2 ) 
We know that a = 1, b = - 5, and c = - 4 from the equation " 
" ( which can be rewritten in the form 
). Therefore, simply plug in these values into the quadratic formula to receive two solutions:
- This is our positive solution
__________
- And this is our negative solution
You can see that - 0.7 is the negative real number solution to Joline's quadratic equation!
Answer:
C
Step-by-step explanation:
Rectangle: 8*5=40
Triangle 1: (3*5)/2=7.5
Triangle 2: (3*5)/2=7.5
Trapezoid : 40+7.5+7.5=55
The measure of angle z is 27
False
Concentric circles and spheres are those that share the same center. The center of one sphere may be on the circumference of the other while they have the same radius. In that case, they would not be concentric.
