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
0.6875 or 68.75% (69% if you round up)
The table is attached below
<em><u>Solution:</u></em>
Given that,
y = 4x + 8
We have to make a table of value
<em><u>When, x = 0</u></em>
y = 4(0) + 8
y = 8
<em><u>When, x = 1</u></em>
y = 4(1) + 8
y = 4 + 8
y = 12
<em><u>When, x = 2</u></em>
y = 4(2) + 8
y = 8 + 8
y = 16
<em><u>When, x = 3</u></em>
y = 4(3) + 8
y = 12 + 8
y = 20
The table is attached below
y= -1/2x-3
y= -7/3x-5
Slope intercept form is y=mx+b. M is the slope and B is the y-intercept.
I hope that this helps
I believe its 116,464 km?
