Answer:
Area = 72.62 m²
Step-by-step explanation:
Area of a triangle with the given three sides is given by,
Area =
Here, s =
And a, b, c are the sides of the triangle.
From the question,
a = 20 m, b = 10 m and c = 15 m
s =
s = 22.5
Substitute these values in the formula,
Area =
=
=
= 72.62 m²
Pull out your reference sheet that has the Pascal's Triangle.
Step 1) Locate the row that starts with 1, 8, ... If this row isn't shown, then you'll need to find a bigger Pascal's Triangle.
Step 2) Count out exactly five spaces starting at the first value 1. Why five? Because we start at 0 instead of starting at 1. The first value in the row represents
while the second value in that row represents
and the third value represents
and so on. So the value
is in the fifth slot from the left.
You should land on the value
70, which is the final answer
Answer:
..D).... x = 8..
Step-by-step explanation:
..x = 8..
<span>a rate of change of –8
so
27 - 8 = 19
19 - 8 = 11
