Substitute the values
-2(-2)^2+4(3)
First evaluate the exponent.
-2(4)+4(3)
Then evaluate multiplication.
-8+4(3)
-8+12
Then add.
Final answer:4
The triangle has a base of 7 so 1/2 the base is 3.5.
The height = 7.5 (from graphic)
Area of "left triangle" = 3.5*7.5 / 2 =
<span>
<span>
<span>
13.125
</span>
</span>
</span>
The entire triangle area = 2 * 13.125 =
26.25
Triangle perimeter both legs = 16.6 + base (7) = 23.6
Answer:
-2.125
Step-by-step explanation:
$434
Step by step explanation:
$14.00 X 20h = 280
14.00 X 5h =70
$14.00 X 6h=84
Add all of those and it is 434
