Answer:
-12x+18x²
Step-by-step explanation:
Given:
Distributive property of multiplication under which a number is multiplied by the sum of two number, the first number can be distributed to both of those number.
∴
solving it by using distributive property
=
=
Opening parenthesis
=
Hence, -12x+18 is the result after using distributive property.
Answer:
a^2 + b^2 = c^2
3^2 + b^2 = 5^2
9 + b^2 = 25
b = _/16
b = 4

Answer: Hello mate!
Let's define the variable t as the time, and define t = 0 as the moment when the first skater starts to move:
We know that the speed of the first skater is 8 m/s, and we need to find the position as a function of time, then we need to integrate the velocity over time
if v1(t) = 8m/s
then p1(t) = (8m/s)*t
now we also know that the second skater has a velocity of 9m/s and enters in the frozen lake at t= 10s.
then the velocity of the second skater is: v2(t) = 9m/s, and the position is:
p2(t) = (9m/s)*(t - 10s)
now we want to know how many seconds after the second skater starts are needed for the second skater to overtake the first one.
this is equivalent to see when his positions will be equal.
so p1(t) = p2(t):
(8m/s)*t = (9m/s)(t - 10s) = (9m/s)*t - 90m
(8m/s)*t - (9m/s)*t = -90m
(-1m/s)*t = 90m
t = 90m/(1m/s) = 90s
Then in t = 90 seconds, the second skater will overtake the first one, and knowing that the second skater started at t = 10 seconds; there are 80 seconds after the second skater started needed to overtake the first skater.
Answer:
48
Step-by-step explanation:
Here we will show you how to calculate 8 divided by 1/6. We will give you the answer in fraction form and in decimal form.
Here is 8 divided by 1/6 displayed mathematically in colors:
8
÷
1
6
The numbers in 8 divided by 1/6 are labeled below:
8 = whole number
1 = numerator
6 = denominator
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:
8 x 6
1
=
48
1
Thus, the answer to 8 divided by 1/6 in fraction form is:
48
1
To make the answer to 8 divided by 1/6 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:
48 / 1 = 48
The answer is rounded to the nearest two decimal points if necessary.
48/1 is an improper fraction and should be written as 48.
