Aheptagon has one side that is 16x2 + x - 17 units in length,
another side that is 2x2 – 9x – 14 units in length, and two sides that are each
4x2 -- 5x + 3 units long. if each of this heptagon's remaining sides has a
length of 11x2 - 2x + 9 units, what simplified expression represents the
perimeter of this heptagon?
the perimeter of the heptagon is ?

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

answer: the value of x is 7cm

step-by-step explanation:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
