(X+4)^2-3(x+4)-3=0
Select the solutions of the og equation
Answer:
[tex]\boxed{\textsf{ The value of x is }\bf{ \dfrac{-5\pm\sqrt{21}}{2}}.}[/tex]
Step-by-step explanation:
A quadratic equation is given to us and we need to find the Solutions of the quadratic equation . So the given equⁿ is ,
[tex]\sf\implies (x+4)^2 -3(x+4) -3 = 0 [/tex]
Firstly let's simpify the quadratic equation and then use the quadratic formula also known as " Shreedhacharya's Formula" .
Taking the given equation :-
[tex]\sf\implies (x+4)^2 -3(x+4) -3 = 0\\\\\sf\implies x^2 + 16 + 8x -3x -12 -3 = 0 \\\\\sf\implies x^2+5x +1 = 0 [/tex]
Now let's use the Quadratic formula ,
Quadratic Formula :-
[tex]\qquad\boxed{\boxed{ \sf x =\dfrac{ -b \pm \sqrt{ b^2-4ac}}{2a} }} [/tex]
With respect to Standard form ax² + bx + c form. Here a = 1 , b = 5 and c = 1 .
[tex]\sf\implies x = \dfrac{ -5\pm \sqrt{ (5)^2-4(1)(1)}}{2(1)} \\\\\sf\implies x = \dfrac{ -5 \pm \sqrt{ 25 -4 } }{2} \\\\\sf\implies \boxed{\pink{\sf x = \dfrac{-5+\sqrt{21}}{2}, \dfrac{-5-\sqrt{21}}{2} }}[/tex]

[tex]\sqrt{290}\approx 17.0\text{ units}[/tex]
B)
[tex]\sqrt{53}\approx7.3\text{ units}[/tex]
Step-by-step explanation:
To find the distance between any two points, we can use the distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
Problem 1)
We have the two points (-4, 5) and (7, 18).
Let (-4, 5) be (x₁, y₁) and let (7, 18) be (x₂, y₂).
Substitute:
[tex]d=\sqrt{(7-(-4))^2+(18-5)^2}[/tex]
Evaluate:
[tex]\begin{aligned}d&=\sqrt{(11)^2+(13)^2}\\&=\sqrt{121+169}\\&=\sqrt{290}\approx17.0\end{aligned}[/tex]
Problem 2)
We have the two points (-2, -3) and (-4, 4).
Similarly, we will let (-2, -3) be (x₁, y₁) and (-4, 4) be (x₂, y₂).
Substitute:
[tex]d=\sqrt{(-4-(-2))^2+(4-(-3))^2[/tex]
Evaluate:
[tex]\begin{aligned}d&=\sqrt{(-2)^2+(7)^2}\\&=\sqrt{4+49}\\&=\sqrt{53}\approx7.3\end{aligned}[/tex]

A number squared is just the number times itself.
[tex]n(n)=n^2[/tex]
Answer:
A number squared is a number to the power of 2 or the number times itself.
Step-by-step explanation:
Lets say you have a 4 to the 2nd that would mean that the 4 is multiplied by 4. Dont get the exponent confused as the number to multiply it as. Look at [tex]9^{2}[/tex] for example, you would multiply the number 9 2 times not 9 times 2 so it would be 9x9.

Answer:
y = 3x + 11
Step-by-step explanation:
obviously since y is 11 when x is zero the constant term is 11.
Then use the other coordinates to find the cooefficent of x.
-4= c × -5 + 11
-4= -5c + 11
5c=15, c=3
Therefore the equation should be:
y= 3x + 11

Answer:
y = 6/5x -5
Step-by-step explanation:
Points are (5,1) (0,-5)
-5 - 1/ 0-5 = 6/5 slope
y-y1= m(x-x1)
y- 1 = 6/5(x-5)
y -1 = 6/5X - 6
y = 6/5X -5

Solve the following equation:
1.3(a + 2) + 5.6 = 17.3
Answer:
a=7
Step by step Explanation:
Step 1: Simplify both sides of the equation.
1.3(a+2)+5.6=17.3
(1.3)(a)+(1.3)(2)+5.6=17.3(Distribute)
1.3a+2.6+5.6=17.3
(1.3a)+(2.6+5.6)=17.3(Combine Like Terms)
1.3a+8.2=17.3
1.3a+8.2=17.3
Step 2: Subtract 8.2 from both sides.
1.3a+8.2−8.2=17.3−8.2
1.3a=9.1
Step 3: Divide both sides by 1.3.
1.3a 9.1
1.3 = 1.3
a = 7
