Step-by-step explanation:
To find - Alicia is solving a quadratic equation. She wants to find the value of x by taking the square root of both sides of the equation. Which equation allows her to do this?
a.) x2+81x+18=54
b.) x2−8x+24=17
c.) x2+9x−24=25
d.) x2+16x+64=36
Proof -
The correct answer is - d.) x2+16x+64=36
x2+16x+64=36
⇒x² + 8x + 8x + 64 = 36
⇒x(x + 8) + 8(x + 8) = 36
⇒(x+8)(x+8) = 36
⇒(x+8)² = 36
Take square root both sides, we get
√(x+8)² = √36
⇒x + 8 = ± 6
⇒x + 8 = 6, x + 8 = -6
⇒x = 6 - 8 , x = -6 - 8
⇒x = -2, -14
So,
Equation (4) allows her to do the following thing she ants.
Hey please help me this is an Angle sum theorem!!!
Answer:
900° and 1260°
Step-by-step explanation:
The sum of the interior angles of a polygon is calculated as
sum = 180° (n - 2) ← n is the number of sides
(2)
Here n = 7 , then
sum = 180° × 5 = 900°
(3)
Here n = 9 , then
sum = 180° × 7 = 1260°

HELP HELP ASAP!!!!!!!!!!!!!!!!!!!!
how many solutions is there to the system of equations? 2x + 3y = 11 -4x - 6y = -22
Answer:
x = 4, y = -3
Step-by-step explanation:
{2x - y = 11
{x + 3y = -5
You can use the substitution method by solving for x in the second equation:
x + 3y = -5
Subtract 3y from both sides:
x = -3y - 5
Now, substitute this value for x into the first equation:
2x - y = 11
2(-3y - 5) - y = 11
Distribute:
-6y - 10 - y = 11
Add 10 to both sides:
-6y - y = 21
Combine like terms:
-7y = 21
Divide both sides by -7:
y = -3
Next, substitute this value for x into the second equation:
x + 3y = -5
x + 3(-3) = -5
Multiply:
x - 9 = -5
Add 9 to both sides:
x = 4

Answer:
∠ FEG = 50°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
110° is an exterior angle of the triangle, then
5x + 6x = 110
11x = 110 ( divide both sides by 11 )
x = 10
Then
∠ FEG = 5x = 5(10) = 50°
In ⊙Q, mJK=180° and mLM=116°. What is m∠1?
Answer:
64degrees
Step-by-step explanation:
From the given diagram;
m<LK = 180degrees
m<LM = 116degrees
Required
m<1
Since <1 and <LM lies on the same straight line, hence;
m<1 + m<LM = 180
m<1 + 116 = 180
m<1 = 180 - 116
m<1 = 64degrees
Hence the measure of m<1 is 64degrees
Answer: 32
Step-by-step explanation:
2a+180+116=360
2a=64
a=32

What does side DE equal?
first person gets brainliestly answer!
Answer:
Length of line DE = 20
Step-by-step explanation:
The scale factor from ΔABC to ΔDEF is 2.
Line AB is similar to line DE.
So, we need to multiply the length of line AB by 2 to get the length of line DE:
10 × 2 = 20

What is the slope of the line that passes through the points (-5, 8) and (-11, 8)
there is given the numbers equals to 8 and DC equals to 3.2 and BE quals to 9 and find BC
Given:
Consider [tex]AB\parallel DE[/tex] in triangle ABC and [tex]AD=8,DC=3.2,BE=9[/tex].
To find:
The length of BC.
Solution:
Basic proportionality theorem (BPT): If a line intersect the two sides of triangle and parallel to the third side, then that line intersects the other two sides proportionally.
Using Basic proportionality theorem, we get
[tex]\dfrac{AD}{DC}=\dfrac{BE}{EC}[/tex]
[tex]\dfrac{8}{3.2}=\dfrac{9}{EC}[/tex]
On cross multiplication, we get
[tex]8\times EC=9\times 3.2[/tex]
[tex]EC=\dfrac{28.8}{8}[/tex]
[tex]EC=3.6[/tex]
Now,
[tex]BC=BE+EC[/tex]
[tex]BC=9+3.6[/tex]
[tex]BC=12.6[/tex]
Therefore, the length of side BC is 12.6 units.
