Answer:
2(n-12)
Step-by-step explanation:
Answer:
x=0.333
Step-by-step explanation:
12(3x)=12
36x=12
/36 on both sides
x=0.333
Answer:
21 cm
Step-by-step explanation:
Since this is an isosceles triangle, the two sides with a line through them must have the same value of x. Therefore, you can set up the following equation:
2x+11=53
2x=42
x=21 cm
Hope this helps!
Answer:
vertex = (1, - 9 )
Step-by-step explanation:
The x- coordinate of the vertex is at the midpoint of the zeros.
Given
f(x) = (x - 4)(x + 2)
Find the zeros by letting f(x) = 0 , that is
(x - 4)(x + 2) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 4 = 0 ⇒ x = 4
Then
= 
= 
= 1
Substitute x = 1 into f(x) for corresponding y- coordinate
f(1) = (1 - 4)(1 + 2) = (- 3)(3) = - 9
Vertex = (1, - 9 )
Answer:
The distance is 10.5 miles
Step-by-step explanation:
Mathematically; we want to calculate the distance between the two towns in the question
Distance = speed * time
15 minutes to hours is 15/60 = 1/4 hours
So the distance would be;
Distance = 42 mph * 1/4 = 10.5 miles
