Answer:
156
Step-by-step explanation:
1) The formula for finding the sum of interior angles of an n-gon is 180(n-2)
2) Plug in 15 for n
180(15-2)
3) Solve
180(15-2)
180(13)
2340
4) There are 15 angles in a 15-gon
5) Divide sum of interior angles by number of interior angles
2340/15 = 156
6) So, the answer is 156 degrees
Answer:
B) 4y - 2 - 3y = 6
Step-by-step explanation:
x = 4y - 2 Substitute this into the second solution
x - 3y = 6
4y - 2 - 3y = 6
Answer:
w = -1.44 and w = -14.06
Step-by-step explanation:
That "(3) / (4)" in (w+14)/(4w+6)=(3)/(4) looks fishy. Assuming that you really meant 3/4, then we have (w+14)/(4w+6)=3/4.
Mult. both sides by 4 to remove the fraction: 4(w+14)/(4w+6) = 3.
Multiply out (w+14)/(4w+6): 4w^2 + 6w + 56w + 84. Combine the w terms, obtaining 4w^2 + 62w + 84. Then the original equation becomes:
4w^2 + 62w + 84 = 3, or 4w^2 + 62w + 81 = 0.
This is a quadratic equation, with a = 4, b = 62 and c = 81. The two roots (values of
w) are as follows:
-62 plus or minus √(62^2-4(4)(81)
----------------------------------------------------------
8
-62 plus or minus √(2548) -62 plus or minus 50.48
w = ------------------------------------------- = ---------------------------------------
8 8
Simplifying, we get w = -1.44 and w = -14.06
