4x=4, divide both sides by 4

x=1

Need a bit of help with this question:
DiKsa [7]

Firstly let's find hypotenuse(let it will be "n" of smaller triangle

Let use Pythagorean theorem

a^{2}  +  {b}^{2}  =  {n}^{2}  \\  {20}^{2}  +  {10}^{2}  =  {n}^{2}  \\  n =  \sqrt{500}

Now we need to find hypotenuse(x) of bigger triangle

{c}^{2}  +  {n}^{2}  =  {x}^{2}  \\  {9}^{2}  +  { \sqrt{500} }^{2}  =  {x}^{2}  \\ x =  \sqrt{581}

The value of x must be rounded to 1 DP, so

\sqrt{581}  = 24.1039... \\  \sqrt{581}  \simeq \: 24.1

Answer: x=24.1

Somebody... PLEASE help<br><br> What is the only solution of 2x2 + 8x = x2 – 16?
makvit [3.9K]

Answer:

x= - 4

Step-by-step explanation:

2 * x^2 + 8 * x = x^2 - 16

2 * x^2 - x^2 + 8 * x + 16 = 0

x^2 + 8 * x + 16 = 0

(x + 4) * (x + 4) = 0

x = - 4
