Answer:
x = 5
or
x = 3
Step-by-step explanation:
The first term is, x2 its coefficient is 1 .
The middle term is, -8x its coefficient is -8 .
The last term, "the constant", is +15
Step-1 : Multiply the coefficient of the first term by the constant 1 • 15 = 15
Step-2 : Find two factors of 15 whose sum equals the coefficient of the middle term, which is -8 .
-15 + -1 = -16
-5 + -3 = -8
If the equation x²−8x−5=0 can be transformed into the equation (x−p)²=q, then value of q is 21
What is Equation?Two or more expressions with an Equal sign is called as Equation.
To transform the equation x² - 8x - 5 = 0 into the equation (x - p)² = q, we need to complete the square by adding and subtracting a constant term.
First, let's add 5 to both sides to get:
x² - 8x = 5
Applying complete square method
we need to add and subtract 16 inside the parentheses on the left-hand side:
x² - 8x + 16 - 16 = 5
Simplifying the left-hand side gives us:
(x - 4)² - 16 = 5
Adding 16 to both sides gives us:
(x - 4)² = 21
Therefore, the value of q is 21.

If a quadratic has a maximum at (4, 2) with roots at (2,
0) and (6, 0), what is a possible equation?
Answer:
g(x) = - 1/2 * (x^2 - 8x + 12)
Step-by-step explanation:
Given the information, you have provided.
Zeros: (2,0) and (6,0).
Maximum: (4,2) which is also your (h,k)
f(x) = - (x - 2)*(x - 6)
g(x) = - 1/2 * (x^2 - 8x + 12)
I do not know how to explain this, but -1/2 makes the graph get (4,2) as the maximum.
The red graph is f(x) = - (x - 2)*(x - 6)
The blue graph is your answer g(x) = - 1/2 * (x^2 - 8x + 12)

Will a 12-inch ruler fit in a box that is a right rectangular prism with a width of
5 inches, a length of 10 inches, and a height of 3 inches? Explain your answer
Answer:
The Ruler won't fit.
Step-by-step explanation:
Remark
The way this is traditional done is to find the hypotenuse of 5 and 10 inches and use this result with the height. If that does not work, then other combinations can be used.
Hypotenuse (10 and 5 )
Formula
c^2 = a^2 + b^2
Givens
a = 10
b = 5
Solution
c^2 = 10^2 + 5^2 Expand
c^2 = 100 + 25 Add
c^2 = 125
Now use the Pythagorean Theorem a second time.
z^2 = x^2 + y^2
x^2 = 125
y^2 = 3^2
z^2 = 125 + 9
z^2 = 134
This is not large enough. A ruler is 12 inches long which would mean that z^2 should come to 144. I don't think any other combination is going to do much better.
In fact looking at it more closely all combinations will give z^2 = 134.

Find the value of x.
Answer:
51°
Step-by-step explanation:
to find x, note that the sum of angles in a triangle is equal to 180°
x+ 63° +66° = 180° ( sum of angles in a triangle.)
x+129° = 180°
x= 180-129 = 51°
x= 51°

[tex]3\left(q-7\right)=27[/tex]
Answer:
Solution of equation ( q ) = 16Step-by-step explanation:
In this question we have given an equation that is 3 ( q - 7 ) = 27 and we have asked to solve this equation that means to find the value of q .
Solution : -
[tex] \quad \: \longmapsto \: 3(q - 7) = 27[/tex]
Step 1 : Solving parenthesis :
[tex]\quad \: \longmapsto \:3q - 21 = 27[/tex]
Step 2 : Adding 21 on both sides :
[tex]\quad \: \longmapsto \:3q - \cancel{ 21} + \cancel{21} = 27 + 21[/tex]
On further calculations we get :
[tex]\quad \: \longmapsto \:3q = 48[/tex]
Step 3 : Dividing by 3 from both sides :
[tex]\quad \: \longmapsto \: \frac{ \cancel{3}q}{ \cancel{3}} = \cancel {\frac{48}{3} }[/tex]
On further calculations we get :
[tex]\quad \: \longmapsto \: \pink{\boxed{\frak{q = 16}}}[/tex]
Therefore, solution of equation ( q ) is 16 .Verifying : -
Now we are very our answer by substituting value of q in the given equation . So ,
3 ( q - 7 ) = 273 ( 16 - 7 ) = 273 ( 9 ) = 2727 = 27L.H.S = R.H.SHence, Verified.Therefore, our solution is correct .

The value of q is 16[tex] \: [/tex]
Step-by-step explanation:
So here, a equation is given and we are asked to solve the equation.
[tex] \\ \dashrightarrow \sf \qquad3(q-7)=27 \\ \\ [/tex]
For this, we have to use the Distributive property, which is :
a(b + c) = ab + ac[tex]\\ \dashrightarrow \sf \qquad3q-21=27 \\ \\ [/tex]
Transposing the constant term (-21) to the right side we get :
[tex]\\ \dashrightarrow \sf \qquad3q=27 + 21 \\ \\ [/tex]
Adding the like terms :
[tex] \\ \dashrightarrow \sf \qquad3q=48 \\ \\ [/tex]
Now, We'll divide both sides by 3 :
[tex] \\ \dashrightarrow \sf \qquad \frac{3q}{3} = \frac{48}{3} \\ \\ [/tex]
[tex]\dashrightarrow \bf \qquad \: q=16 \\ \\ [/tex]

Answer:
measure of angle EFG = 139°
measure of angle IFH = 49°
Since angles DEF and EFG are supplementary:
[tex]2x + 3 + 6x + 25 = 180[/tex]
[tex]8x + 28 = 180[/tex]
[tex]8x = 152[/tex]
[tex]x = 19[/tex]
So the measure of angle EFG is
6(19) + 25 = 114 + 25 = 139 degrees, and the measure of angle DFE is 41 degrees.
Angles DFE and GFH are vertical, so angle GFH measures 41 degrees.
Angles GFH and IFH are complementary, so angle IFH measures 49 degrees.

Answer:
[tex]m=\frac{y-b}{x-a}[/tex]
Step-by-step explanation:
Considering no values were supplied, the most we can do here is rearrange the equation to get m on its own.
In the equation y - b = m(x - a), since (x - a) is multiplicative of m, we can divide this value to remove it from m's side. This leaves us with:
[tex]m=\frac{y-b}{x-a}[/tex]
