Answer:
I would say you first simplify it to x<-8
sooo The answer is A
<span>(5x-6)(5x+6)
= (5x)^2 - 6^2
= 25x^2 - 36</span>
Answer:
One's place
Step-by-step explanation:
The area of the hexagonal planter is 10.32 m²
<h3>Regular hexagon</h3>
Regular hexagon are polygon with 6 sides and are equiangular. This means the angles are the same.
area of hexagon = 1 / 2 × apothem × perimeter of hexagon
apothem = 1.72 m
side length = 2 m
area of hexagon = 1 / 2 × 1.72 × 6(2)
area of hexagon = 1 / 2 × 1.72 × 12
area of hexagon = 20.64 / 2
area of hexagon = 10.32
area of hexagon = 10.32 m²

A) By Pythagoras' Theorem x^2 = 13^2 - 5^2 where x = length of the other leg. x^2 = 169 - 25 = 144 so x = 12. cms.
b) perimeter = 5 + 12 + 13 = 30 cms
c) Area of triangle = product of the 2 legs = 5*12 = 60 cm^2.
