Add 9 to both sides to get the x-value alone
x-9=-5
x=4
Answer: 67.725feet²
Step-by-step explanation:
A heptagon consist of 7 sides and Its area is calculated using the formula
= 1/2 × nsr
n = number of sides = 7
s = side length = 4.3
r = apothem = 4.5
Area = 1/2 × nsr
= 1/2 × 7 × 4.3 × 4.5
= 0.5 × 7 × 4.3 × 4.5
= 67.725feet²
The question is saying that the line KJ is approximately equal to the line JN and that the line JN is perpendicular to the line NL. The line labeled LKN is shorter than LNK due to the fact that the line segments in LNK are longer because JN is perpendicular to NL:)
Answer:
7 + 7n
Explanation:
Seven more (7 plus) the product of 7 and a number (seven times n) = 7 plus 7n
Answer:
the missing side lenght = x
0 < x < 15+10
0 < x < 25 cm
