HELPP Find the side length x . Round to the nearest hundredth

polet [3.4K]

Answer:

x = 11.18

Step-by-step explanation:

According to the Pythagorean Theorem; (Leg1)² + (leg2)² = (Hypotenuse)²

10² + x² = 15²

100 + x² = 225

x² = 125

x = $\sqrt{125}$

x = 11.18

Hope this helps!

If x > 3, which of the following is equivalent

monitta

Answer:

B

Step-by-step explanation:

Let's simplify the given function.

$\frac{1}{\frac{1}{x+2} +\frac{1}{x+3} }$
$\frac{1}{\frac{x+3+x+2}{(x+2)(x+3)} }$
$\frac{(x+2)(x+3)}{2x+5}$

Now, let's take x = 4 as it is given x > 3.

(4 + 2)(4 + 3)/2(4) + 5
6(7)/13
42/13

Without evaluating, we can see the answer is B because on multiplying the factors in the numerator is simplified to the answer given in the option.

If (x/100-1)(x/100+1)=kx^2-1 k=

Artist 52 [7]

(x/100-1)(x/100+1)=kx^2-1
(x/100-1)(x/100+1)=(x/100)^2 - 1^2 because it's a difference of squares ( (a-b)(a+b) = a^2-ab+ab-b^2 = a^2 - b^2):
(x/100)^2 - 1^2=kx^2 - 1
(x/100)^2 - 1=kx^2 - 1
(x/100)^2=kx^2
(x^2)/(100^2)=kx^2
1/(100^2)=k
1/10000=k
k=0.0001
