Answer:

The square root of 253.

Step-by-step explanation:

using the Pythagorean theorem, 6 squared plus JL squared equals 15 squared. Backtracking, we get that JL is the square root of 189. Now, JL squared plus 8 squared is the length of JK squared. 189 plus 64 is 253. The length of JK is thus the square root of 253.

consider the function f(x) = x2 2x – 15. what are the x-intercepts of the function? left-most x-intercept: ( , 0) right-most x-i

eimsori [14]

we have

$f(x)=x^{2} +2x-15$

we know that

The x-intercept is the value of x when the value of the function is equal to zero

in this problem

Find the roots of the function

equate the function to zero

$x^{2} +2x-15=0$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$x^{2} +2x=15$

Complete the square. Remember to balance the equation by adding the same constants to each side

$x^{2} +2x+1=15+1$

$x^{2} +2x+1=16$

Rewrite as perfect squares

$(x+1)^{2}=16$

Square root both sides

$(x+1)=(+/-)\sqrt{16}$

$(x+1)=(+/-)4$

$x=-1(+/-)4$

$x1=-1+4=3$

$x2=-1-4=-5$

$x^{2} +2x-15=(x-3)(x+5)$

therefore

<u>the answer is</u>

the x-intercepts are the points $(3,0)$ and $(-5,0)$

Use the commutative property to simplify the expression 4/3 + 3/4 + 2/3

saw5 [17]

The simplified expression using the commutative property is : $\frac{6}{3}$ + $\frac{3}{4}$

<h3>Meaning of commutative property</h3>

commutative property can be defined as a mathematics attribute that is possessed by a mathematical equation, that enables the objects undergoing addition or multiplication to change position.

In conclusion, The simplified expression using the commutative property is : $\frac{6}{3}$ + $\frac{3}{4}$

<h3>Analysis</h3>

4/3 + 3/4 + 2/3 = ( $\frac{4}{3}$ + $\frac{2}{3}$ ) + $\frac{3}{4}$ = $\frac{6}{3}$ + $\frac{3}{4}$
