Answer:15
Step-by-step explanation: 7 and a half times 2 is 15
Answer:
The height is 4.472
Step-by-step explanation:
That formula is Heron's formula.
Where "s" is calculated like this:
s = (a + b + c) / 2
In this case:
a = 14
b = 12
c = 6
replacing:
s = (14 + 12 + 6) / 2
s = 16
Now we calculate the area:
A ^ 2 = 16 * (16−14) * (16−12) * (16−6)
A ^ 2 = 1280
A = 35.777
The area of the triangle is:
A = b * h / 2
In this case we will take the base as the longest side of the triangle, that is to say = 14
Thus:
h = A * 2 / b
h = 35.777 * 2/16
h = 4.472
So the height is 4.472
The transformed equation is:
Step-by-step explanation:
We have to convert the equation in the form
Given equation is:
Adding 8 on both sides
In the given equation
a = x
b= ?
So,
So 3^2 will be added on both sides
Hence,
The transformed equation is:
