Answer:
84 cm^2
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh where b is the length of the base and h is the height
A = 1/2 ( 5+9) * 12
A = 1/2 (14) * 12
A =84
To make this easier, first draw or imagine a vertical line at x=2
Find where the vertical line and the graph intersects.
Draw or imagine that point of intersection.
Now, draw or imagine a horizontal line that goes through the point of intersection.
That horizontal line tells us the the value of the function by passing through that mark that says "-2"
The function's value at x=2 is -2.
Have an awesome day! :)
<span> iscoseles triangle
</span>
3x - 5 = 19 - x
4x = 24
x =6
3x - 5 = 3(6) -5 = 13
2x = 2(6) = 12
perimeter of <span> iscoseles triangle
P = 2a + b
P = 2(13) + 12
P = 26 + 12
P = 38
answer
Perimeter = 38 cm</span>
