Here we are given the three sides of the triangle.
So we have Heron's formula to find its area.
Heron's formula is given by :

where A, B and C are sides of triangle and S is semi perimeter which is given by,

plugging values of A, B and C to find S

S=13.5
Now plugging values of A, B , C and S in Heron's formula

A=26.14 mm²
Answer: Area of triangle is 26.14 mm².
Answer:
(b) -m, m + 3
Step-by-step explanation:
x² − 3x − m(m + 3) = 0
x² − 3x = m(m + 3)
x² − 3x + 9/4 = m(m + 3) + 9/4
(x − 3/2)² = m(m + 3) + 9/4
(x − 3/2)² = m² + 3m + 9/4
(x − 3/2)² = (m + 3/2)²
x − 3/2 = ±(m + 3/2)
x − 3/2 = m + 3/2, -m − 3/2
x = m + 3, -m
Approximately 61.
if you divide 420 by 6.82 you get 61.58 :)
Answer:
Step-by-step explanation:
There are many such polynomials, but the one with leading coefficient of 1 is
y = (x+1)(x-1)(x-6) = x^3 - 6x^2 - x + 6
Not sure what you want to do with the 5, If that is the y-intercept, then since
(1)(-1)(-6) = 6, we will need
y = 5/6 (x^3 - 6x^2 - x + 6)
Your answer is c, an obtuse triangle because if the two side lengths are the same length along with a longer side, it become obtuse
