Answer:
it's 6
Step-by-step explanation:
B=7 and D=13, so 13-7= 6
The first one.
Hope this helps :)
Answer:
pretty sure it's B, its just really hard to see
Step-by-step explanation:
The resulting equation on using the completing the square is y = (x+5)² - 25
<h3>Completing the square method</h3>
The quadratic equation has a leading degree of 2. Given the equation below;
y = x^2+10x
Add the square of the half of coefficient of x to have;
y = x^2+10x + (10/2)²- (10/2)²
y = x^2 + 10x + 5² - 5²
y = x^2 + 10x + 25 - 25
y = (x+5)² - 25
Hence the resulting equation on using the completing the square is y = (x+5)² - 25

<span>Exponent
is a number used to express shorter equation; it is a number that says how many
times you are going to multiply the base number.

Exponents have several laws, here are
some:
=> x^1 = x
=> x^0 = 1
=> x^-1 = 1/x
=> x^m x^n = X^m+n
=> x^m/x^n = x^m-n
And since we were asked to write an
expression with a negative exponent that has a value between 0 and ½
=> 2^ -2 = ½
