Estimation involves rounding
3/8 is closest to 4/8 which is 1/2, or 6/12
6/12 + 1/12 = 7/12
that is the estimated answer
Answer:
see explanation
Step-by-step explanation:
The perimeter is the sum of the 3 sides, that is
perimeter = 8 + 12 + 17 = 37 cm
To use Heron's formula for area (A)
A = 
where a, b and c are the lengths of sides and s the semi perimeter
s = 37 ÷ 2 = 18.5
let a = 8, b = 12 and c = 17, then
A = 
= 
= 
≈ 43.52 cm² ( to 2 dec. places )
<h2><u>Polynomial Function</u></h2>
<h3>Evaluate the following function: Show all work! h(x)=3x²+2-2x, Find h(-2)</h3>
To determine the answer, substitute the given value to the function and simplify.
- h(x) = 3x² + 2 - 2x; h(-2)
- h(-2) = 3(-2)² + 2 - 2(-2)
- h(-2) = 3(4) + 2 + 4
- h(-2) = 12 + 2 + 4
- h(-2) = 14 + 4
- h(-2) = 18

Answer:
__2_sides of equal length
__2_acute angels
__0_right angle(s)
_1__obtuse angle
The triangle is _isosceles____and_obtuse____.
Step-by-step explanation:
if this is the right triangle the longest side will be √162≈ 12.7
the longest side is 15 so the vertex angle is obtuse
