In an isosceles triangle, two sides are equal to each other. So, we know that the third side is either 6 or 15 inches.
If the third side is 6 inches, it would not make a triangle. The sum of any to sides of a triangle must be larger than the third side. However, 6+6 is LESS than 15, so 6 inches would not be the answer.
By process of elimination, the third side is 15 inches. Good luck!
Answer is (4x³ - 6)(16x² + 36 + 24x³)
X - Linda's speed
(x+8 )- Colleen's speed
8x - Linda's distance for 8 h
8(x+8) = 8x+64 - Colleen's distance for 8 h
8x + 8x + 64 = 176 - distance between Colleen and Linda after 8 h
8x + 8x + 64 = 176
16x +64 = 176
16x = 176 - 64
16x = 112
x= 7 mph Linda's speed
x+8 = 7+8 = 15 mph Colleen's speed
Answer:
You don't have enough money for 2 downloads
Step-by-step explanation:
The cost of downloading one movie is ...
g(1) = 2·1 = 2 . . . dollars
The cost of downloading one song is ...
f(1) = (1/2)(1) +2 = 2.50 . . . dollars
Downloading 2 songs, 2 movies, or one of each will cost more than $2.50.
You don't have enough money for 2 downloads.
