Answer: x = 10 <em>OR</em> x = 4.
Step-by-step explanation: If x = 10 or 4 then the last step of the equation will always be multiplying by 0 which equates to 0 as well.
if x = 10
(10-10)(10-4) -> (0)(6) -> 0 x 6 = 0
if x = 4
(4-10)(4-4) -> (-6)(0) -> -6 x 0 = 0
Answer:
<em>x ≈ 6.5 , y ≈ 12.1</em>
Step-by-step explanation:
(2x)² + (10.2)² = (16.5)²
4x² = 272.25 - 104.04
x² = 168.21 ÷ 4
<em>x</em> = √(42.0525) ≈ <em>6.5</em>
y² = 42.0525 + 104.04 = 146.0925
<em>y</em> = √(146.0925) ≈ <em>12.1</em>
Answer:
option a is the answer
Step-by-step explanation:
put the value of x in each expression as x = -2
you'll see that in option a the expression becomes
![\frac{x - 3}{ {x}^{2} - 4} = \frac{ - 2 - 3}{ {( - 2)}^{2} - 4} \\ = \frac{ - 5}{4 - 4} \\ = \frac{ - 5}{0}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%20-%203%7D%7B%20%7Bx%7D%5E%7B2%7D%20%20-%204%7D%20%20%20%3D%20%20%20%5Cfrac%7B%20-%202%20-%203%7D%7B%20%7B%28%20-%202%29%7D%5E%7B2%7D%20%20-%204%7D%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B%20-%205%7D%7B4%20-%204%7D%20%5C%5C%20%20%3D%20%20%20%5Cfrac%7B%20-%205%7D%7B0%7D%20%20)
which is not defined. hence -2 is excluded value
Answer:
118.2
Step-by-step explanation:
1.1m is 100%
2.4m×100=240
240/1.1= 218.(18)
218.(18)%-100%=118.(18)=118.2
