Answer:
p = 10
Step-by-step explanation:
In order to solve an equation we must isolate the variable we're solving for, p.
We can do this by undoing operations in the equation.
First, multiply both sides of the equation by 14.
This gives you 4 + p = 14
Then, you can subtract 4 from both sides:
4 - 4 + p = 14 - 4
p = 10
Answer:
42
Step-by-step explanation:
Solving the square root by factorization:
1764 = 2² × 3² × 7²
will be 
= 2 × 3 × 7 =42

It is asking you to find the sum of k^2 - 1 from k=1 to k=4. Since that is only 4 numbers, calculating the sum by hand wouldn’t be that bad.
(1^2 - 1) + (2^2 - 1) + (3^2 - 1) + (4^2 - 1) = 26
The easier way to find the sum is to use a few simple formulas.
When we have a term that is just a constant c, the formula is c*n.
When we have a variable k, the formula is k*n*(n+1)/2.
When we have a squared variable, the formula is k*n*(n+1)*(2n+1)/6.
In this case, we have a squared variable k^2 and a constant of -1.
So plug in n=4 to the formulas:
4*5*9/6 - 1*4 = 26
The answer is 26
Answer:
= 3.5 * 3.5 = 12
square means: multiply the number <u>by itself</u> two times. so 3.5 * 3.5
cube (
) means: multiply the number by itself three times. so 3.5 * 3.5 * 3.5
i hope u understand :)
