Answer:
The answer to your question is -5k⁶
Step-by-step explanation:
Polynomial
- z³ + 5k⁶ - (-z³ + 10k⁶)
Use law of signs for the parenthesis
- z³ + 5k⁶ + z³ - 10k⁶
Use associative property for like terms
(-z³ + z³) + (5k⁶ - 10k⁶)
Simplify like terms
(0) + (-5k⁶)
Result
-5k⁶
So... hmmm if you check the first picture below, for 2)
we could use the proportions of those small, medium and large similar triangles like

now.. for 3) will be the second picture below
5.28 / 12 = 0.44 per oz
7.96 / 18 = 0.4422 rounds to 0.44 per oz
technically, by rounding to the nearest cent, they are the same cost.

diameter = 4m
radius = 4/2
= 2m
volume = (3.14)(2^2)(6.3)
= 79.128m^3
Answer:
3 feet
Step-by-step explanation:
A 12-foot ladder is leaning across a fence and is touching a higher wall located 3 feet behind the fence. The ladder makes an angle of 60 degrees with the ground.
ladder is 12 foot
The ladder makes an angle of 60 degrees with the ground.
It form a right angle triangle . ladder is the hypotenuse


multiply 12 on both sides
x= 6
the distance from the base of the ladder to the bottom of the fence
x-3 = 6-3=3 feet
