The answer is 192 y^8.
(4y^2)^3 = 64y^6
64y^6 • 3y^2= 192y^8
When “multiplying” a number with an exponent, you add the 2 exponents.
Answer:
18,80,82
Step-by-step explanation:
82^2= 6724
18^2+ 80^2= 6724
The square of the largest number is equal to the sum of the squares of the two smaller numbers.
Answer:
x = 14
Step-by-step explanation:
I don't know which one you are supposed to solve it by so I will do both.
Solution by Cross Multiplication
For the equation
7x=24
The cross product is
7×4=x×2
Solving for x
x=7×42
and reducing
x=14
Solution by Proportion
Since the equation is an equality
If
7 ÷ 2 = 3.5
Then it is true that
x ÷ 4 = 3.5
Solving for x
x = 4 × 3.5
x = 14
Answer: The answer is 100 to 140 feet.
Step-by-step explanation: Given that we are anchoring our boat and the water is 20 feet deep. We are to calculate the anchor line we should use.
General rule of calculating anchor line is given by
Multiplying the depth of the water by 5 to 7 . For example, if the water depth is 'x' feet, then we will multiply 'x' feet by 5 to 7 to get the amount of anchor line to put out.
Here, the depth of water = 20 feet.
So, the anchor line should be 5 × 20 to 7 × 20 feet, i.e., 100 to 140 feet.
Thus, the anchor line should be 100 to 140 feet.
