Answer:
The area of the triangle is 7.5 unit²
Step-by-step explanation:
Here we have the coordinates given as
(-3, 5) (-3, 8) and (2, 5)
Let us call the points A = (-3, 5)
B = (-3, 8) and
C = (2, 5)
Therefore the lengths of the sides of the triangle are
AB = a =
AC = b =
BC = c =
Therefore the Area can be derived from Heron's formula which is
A = where s = semi perimeter or (a + b + c)/2
Therefore, plugging the values, we get
s = (3 + 5 + √34)/2 = 6.9155≈6.92
A = = 7.499≈7.5.
Answer:
Answer: 3x² - 7
Step-by-step explanation:
We have to divide 15x³ - 35x by 5x.
This can be done as follows:
Splitting the given fraction, and simplifying the fractions we get:
Therefore, we get 3x² - 7 as our answer when the give polynomial is divided by 5x
