What is the answer to x^2-11=25 please

Westkost [7]

Hey there!

$\mathsf{x^2 - 11 = 25}$

$\large\textsf{ADD 11 to BOTH SIDES}$

$\mathsf{x^2 - 11 + 11 = 25 + 11}$

$\large\textsf{CANCEL out: -11 + 11 because that gives you 0}$

$\large\textsf{KEEP: 25 + 11 because that helps solve for the x-value}$

$\mathsf{25 + 11 = \bf 36}$

$\large\textsf{NEW EQUATION: }\mathsf{x^2=36}$

$\large\textsf{Take the square root of the number (36)}$

$\mathsf{x = \pm \sqrt{36}}$

$\mathsf{\pm = \boxed{\bf plus-or-minus}}$

$\mathsf{x = \sqrt{-36}\rightarrow \bf -6}$

$\large\textsf{or}$

$\mathsf{x = \sqrt{36} = \bf 6}$

$\boxed{\boxed{\huge\textsf{Answer: \bf x = 6 or x = -6}}}\huge\checkmark$

$\large\text{Good luck on your assignment and enjoy your day!}$

Solve each system using substitution: 1. 4x - 5y= -15 y= -3x + 22

Bumek [7]

4x - 5y = -15
y = -3x + 22

Plug in your y= equation into the y variable in the other equation

4x - 5 (y) = -15
^^
y = (-3x + 22) = -15

4x - 5 (-3x + 22) = -15

Distribute

4x + 15x - 110 = -15

Combine like terms and add 110 over to -15

19x = 95

Then, divide the whole equation by 19

x = 5

Then, plug in your x into your y= equation

y = -3 (5) + 22
y = -15 + 22
y = 7

x = 5
y = 7
(5, 7)

The hypotenuse of the right triangle is 5 meter long. the shorter leg is 1 Meter shorter than the longer leg. find the side leng

Firlakuza [10]

Shorter leg = x

Longer leg = x +1

Length of the hypotenuse: 5 m

We can use the pythagorean theorem with the information given. Doing so, we have:

$\begin{gathered} a^2+b^2=c^2 \\ (x)^2+(x+1)^2=5^2\text{ (Replacing the values)} \\ x^2+x^2+2x+1=25\text{ (Raising both terms to the power of 2)} \\ x^2+x^2+2x=25-1\text{ (Subtracting 1 from both sides of the equation)} \\ 2x^2+2x=24\text{ (Adding like terms)} \\ 2x^2+2x\text{ }-24=0\text{ (Subtracting 24 from both sides of the equation)} \\ 2(x+4)(x-3)=0\text{ (Factoring)} \\ x1=-4\text{ (Since x=-4 makes the factor (x+4) equal to 0)} \\ x2=3\text{ (Since x=3 makes the factor (x}-3\text{) equal to 0)} \\ \text{ Since we need a positive solution x would be equal to 3} \end{gathered}$

So, the answers would be:

Shorter leg = 3 m

Longer leg = 4 m

Length of the hypotenuse: 5 m
