X^2 + 12^2 = 13^2
x^2 + 144 = 169 (subtract 144 from both sides)
x^2 = 25 (square root)
x=5

(2x-1)^2=<br><br> Some one plz help.....
Arlecino [84]

Answer: 4x^2−4x+1

Step-by-step explanation:

(2x-1)^2

Square of Difference: (a−b)^​2=a^​2−2ab+b^2.

(2x)^​2−2*2x+1

Multiplication Distributive Property: (xy)^​a=x^{a} y^{a}

2^​​​2x^2−2*2x+1

4x^2−2*2x+1

4x^2−4x+1

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great Valentines Day! :-)

7th term of (c-d)^10
lutik1710 [3]
\bf (c-d)^{10}\implies &#10;\begin{array}{llll}&#10;term&coefficient&value\\&#10;-----&-----&-----\\&#10;1&+1&(c)^{10}(-d)^0\\&#10;2&+10&(c)^9(-d)^1\\&#10;3&+45&(c)^8(-d)^2\\&#10;4&+120&(c)^7(-d)^3\\&#10;5&+210&(c)^6(-d)^4\\&#10;6&+252&(c)^5(-d)^5\\&#10;7&+210&(c)^4(-d)^6&#10;\end{array}

as you notice, the first term from the binomial, starts off with a highest exponent of 10, and then gradually goes down by 1 on every element.

the second term of the binomial, starts off with an exponent of 0, and goes up by 1 on every element.

now, to get the coefficient
the first coefficient is 1 and the second is the same as the binomial's exponent... those two are simple.... now, to get any subsequent one, we simply "get the product of the current coefficient and the exponent of the first term, and divide it by the exponent of the second term on the next element".

for example... how do we get 10 for the second element, basically 1 * 10/1

that one is simple

now how do we get say, 45 for the 3rd element?
10 * 9 / 2

how do we get 252 for the 6th element?
210 * 6 / 5

and so on, and from there, you can expand each element.

Write an expression that would calculated the value of the following account after 14 years: $8100 is invested at an APR of 4.8%
Blizzard [7]

Answer:

  $8100·1.024^28

Step-by-step explanation:

The future value formula is ...

  FV = P(1 +r/n)^(nt)

where P is the principal invested, r is the annual interest rate, n is the number of times per year interest is compounded and t is the number of years. Putting the given numbers in place of the corresponding variables gives the expression you want:

  FV = $8100(1 +.048/2)^(2·14)

  FV = $8100·1.024^28 . . . . . simplified
