Answer:
n = -2
Step-by-step explanation:
we apply distributive property:
-4(8+5n)=8
-4*8 -4*5n = 8
we have:
-32 -20n = 8
we add 32 to both sides of the equation:
-32+32 -20n = 8 +32
we have:
-20n = 40
we divide by -20 to both sides of the equation:
-20n/-20 = 40/-20
we have:
n = -40/20
finally we have:
n = -2
Answer: 8/3, 2 2/3
Step-by-step explanation:
reciprocal of 3/12 is 12/3
soooooo
4/6 x 12/3
which is 48/18
u can divide that by 6
which is 8/3
or 2 2/3
Step-by-step explanation:
The scale factor is 12/6 = 10/5 = 2.
Answer:
15 feet
Step-by-step explanation:
Always draw out a diagram! Especially once you get to physics, its just best to be in the habit. There are a few ways we could solve this problem, but lets stick to the pythagorean theorem. a^2 + b^2 = c^2 .
so in this case, when we substitute its
a^2 + 8^2 = 17^2
a^2 + 64 = 289
a^2 = 225
a = 15
Therefore, the ladder reaches a height of 15 feet against the building.
