Answer:
<h2>
67.7</h2><h2 />
Step-by-step explanation:
perimeter = semicircle (x2) + parallelogram side (x2)
= 1/2 π 12 (x2) + 15 (x2)
= 37.7 + 30
= 67.7
Answer:
18
Step-by-step explanation:
f(x) = 2x^2
Let x = -3
f(-3) = 2 * (-3)^2
Exponents first
f(-3)=2 *9
f(3) = 18
Answer:
Irrational number
Step-by-step explanation:
The number 1.8 isn't repeating so it wouldn't be a repeating rational number.
Assuming this Fence enclosment will be in the shape of a rectangle we will use the equation used to find the area of a rectangle, b×h=a
Using this formula we then must pick out factors used to create, in which the perimeter will add up to 20
·5,5,5,5 (25)
·8,2,8,2 (16)
·6,4,6,4 (24)
using this we can learn<span> that the maximum area that can be exclosed by this is 25, because the 2 perimiter lengths that define this rectangle would be 5 and 5.
</span>b(5)×h(5)=25(a)
therefore, your answer is 25 Units
