X-5 y-4 i am pretty sure from the equations i have worked with
26.4 because .42 you have to leave the 4 the same since the 2 is not greater than 5.
Answer:
36 = x
Step-by-step explanation:
The triangles are congruent by Side Angle Side, so the angles must measure the same
Angle C = Angle E
36 = x
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.
A is amount accrued in one year
to get the interest earned, simply subtract the Principal from the
amount A
