Answer:
A
Step-by-step explanation:
The area (A) of a triangle is calculated as
A =
bh ( b is the base and h the perpendicular height )
Here b = 13 and h = 4 , thus
A =
× 13 × 4 =
× 52 = 26 units² → A
The answer is 2.25 square inches or 7.065 square inches.
Answer:
384/12 or 192/6 or 96/3
Step-by-step explanation:
Find the slope of the line passing throught the points (2, 2) and (4, 3).
The formula of a slope:

Substitute:

If the point (x, -1) lie on the same line, then the slope of line passing through the points (2, 2) and (x, -1) the same:
Substitute:

We have the equation:
<em>cross multiply</em>

<em>add 2 to both sides</em>

<h3>Answer: x = -4.</h3>
