Step-by-step explanation:
every 2 sides of a triangle has to be bigger than the 3rd side
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.
Answer:
She can attend 6 Yoga classes.
Step-by-step explanation:
150 ÷ 13 is about 11.Then multiply 11x 13 and that equals 143. Then you subtract 65 from 143 and you get 78. Then 78 divided by 13 equals 6.
The answer to 4x - 5y = 24 is (6, 0).
