Answer:
10 inches
Step-by-step explanation:
The formula for the triangle area is the following:
A = b * h / 2
Where b is the length of the base side and h is the height.
So, as the height is 4 less than the base, we have that:
h = b - 4
Using this value in the area equation, we have that:
A = b * (b - 4) / 2
30 = (b^2 - 4b) / 2
b^2 - 4b = 60
b^2 - 4b - 60 = 0
Using Bhaskara's formula to solve the quadratic equation, we have:
Delta = 4^2 + 4*60 = 256
sqrt(Delta) = 16
b1 = (4 + 16)/2 = 10
b2 = (4 - 16)/2 = -6 (negative value does not fit for this problem)
So the length of the base is 10 inches.
the answer is x=2 i hope this answers your problem
Answer:What is the 11th term of this geometric sequence 5, 20, 80, 320? In the present GP, a = 5 and r = 20/5 = 4. So the 11th term of the GP = ar^10 = 5*4^10 = 5242880.

Answer:
A. 15
Step-by-step explanation:
LA = πrl
LA = 3.14(1.25)(√3.63^2 + 1.25^2)
LA = 15.06
15.06 ≈ 15
