Answer:
12 days
Step-by-step explanation:
Let the amount of work be x.
John:
6 days = x
1 day =
x
Together:
4 days = x
1 day =
x
Marsha:
1 day =
x -
x
=
x -
x
=
x
=
x
Marsha can do
of the work in 1 day.
No. of days taken (Marsha) = x ÷
x
= 12
A cubic equation has degree 3. That means that the highest exponent of x (or whatever variable is being used) is 3. This means the function can have 0, 1, 2 or 3 roots.
Whatever the highest exponent of the variable is tells us the highest number of roots it can have. It can have that many or fewer but no less than 0.
Answer:
because corresponding parts of congruent triangles ΔACD and ΔACB are Congruent
Step-by-step explanation:
Statements, Reason
bisects ∠BCD, Given
Given
∠CDA ≅ ∠CBA Right angles are ≅
Reflexive property
ΔACD ≅ ΔACB Hypotenuse Leg (HL) congrurency
CPCTC
Where:
CPCTC = Corresponding parts of Congruent Triangles are Congruent
⊥ = Perpendicular to
≅ = Congruent
∠ = Angle
Δ = Triangle.
