Number of solutions: no roots
Type of solution: Not Real
Step-by-step explanation:
We need to identify the number of solutions and their types using the discriminant.
We are given:
Rearranging:
Discriminant can be found by:
where b=-40, a=10 and c=41
Putting values:
So, Discriminant is -40
If the discriminant is less than zero i.e -40 then there are no real roots.
So, Number of solutions: no roots
Type of solution: Not Real
Keywords: discriminant

Answer:
∠6 = ∠8
∠2 = ∠6
Step-by-step explanation:
Lines 'p' and 'q' are the parallel lines and line 'l' is a transversal line intersecting these lines at two distinct points.
By the property of alternate interior angles,
∠3 = ∠5
By the property of vertically opposite angles,
∠6 = ∠8
By the property of corresponding angles,
∠2 = ∠6
Answer:
Sam
30
Step-by-step explanation:
Sam made a mistake when he said . The steps should have been:
You are supposed to square 5 first before multiplying 2. Sam multiplied by 2 first. The correct answer is 30.
Given:
Area(A)= 63m^2
Length (L)= 2W+5
Width (W)=?
A=LxW
63=(2W+5)(W)
63=2W^2 + 5W
0=2W^2+5W-63
0=(2W-9)(W+7)
2W-9=0 then W=4.5 and W+7=0 then W=-7
Can only use 4.5 since it is positive and distance is positive.
W= 4.5 m
L=2W+5=2 (4.5)+5=9+5=14m
Answer:
.15 would be the answer
