Answer:
Step-by-step explanation:
Take half of the coefficient of x (in other words, take half of 12). This results in 6. Square this result, obtaining 36.
Now x2 + 12x = 11 becomes x^2 + 12x + 36 = 11 + 36, or
x^2 + 12x + 36 = 47, or
(x + 6)^2 = 47
Answer:
To complete the square, 36 should be added to both sides.
Step-by-step explanation:
If you have an equation in the form:
ax² + bx + c = ...
Then to complete the square, you want to convert it to this format:
a²x² + abx + (b/2)² = ...
with all instances of x being on the left.
In this case, we're given x² + 12x = 11. Because the first term has no coefficient, completing the square is much simpler. "a" in this case is just 1, which means that "b" is 12 ÷ 1, or just 12. So:
(b / 2)²
= (12 / 2)²
= 6²
= 36
So to actually complete the square, just add 36 to both sides of the equation:
x² + 12x + 36 = 47
(x + 6)² = 47
You can then solve for x quite easily:
(x + 6)² = 47
x + 6 = ±√47
x = -6 ± √47

find the approximate area of the shaded region
Answer:
240.52 m square is your answer
Answer:
B
Step-by-step explanation:
area of square=20×21=420 m²
diagonal=√(20²+21²)=√(400+441)=√841=29
radius=29/2
area of circle=π×(29/2)²=841/4 π≈660.52 m²
area of shaded region=660.52-420=240.52 m²

find the area of triangle CDE the length of the square is 24 meters;
Answer:
288
Step-by-step explanation:
If you didnt know a triangle has the area of a square/2
so basically what im saying is the area of that square/2 equals the area of the triangle
to find the area of the square you take 24 and square it
24^2=576
finally we divide that by 2
576/2=288
so the area of the triangle is 288

The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is five times the measure of the first angle. The third angle is 10 more than the second. Let x, y, and z represent the measures of the first, second, and third angles, respectively. Find the measures of the three angles
Answer:
1st ∡ = 15.5°
2nd ∡ = 77.25°
3rd ∡ = 87.25°
Step-by-step explanation:
1st ∡: x
2nd ∡: y
3rd ∡: z
Equations we can create from data given in problem:
y + z = 5x
z = 5x + 10
We have enough expressions to create an equation:
x + 5x + 5x + 10 = 180
11x = 170
x = 15.5
y = 5(15.5) = 77.25
z = y + 10 = 87.25

Solve by elimination:
3x + 4y = 0
5x-3y = -58
A (6, -8)
B (-6, -8)
C (-8, 6)
D ( 8, 6)
Answer:
x=−8
y=6=
Step-by-step explanation:
3x+4y=0
5x−3y=−58
In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.
3x+4y=0,5x−3y=−58
To make 3x and 5x equal, multiply all terms on each side of the first equation by 5 and all terms on each side of the second by 3.
5×3x+5×4y=0,3×5x+3(−3)y=3(−58)
Simplify.
15x+20y=0,15x−9y=−174
Subtract 15x−9y=−174 from 15x+20y=0 by subtracting like terms on each side of the equal sign.
15x−15x+20y+9y=174
Add 15x to −15x. Terms 15x and −15x cancel out, leaving an equation with only one variable that can be solved.
20y+9y=174
Add 20y to 9y.
29y=174
Divide both sides by 29.
y=6
Substitute 6 for y in 5x−3y=−58. Because the resulting equation contains only one variable, you can solve for x directly.
5x−3×6=−58
Multiply −3 times 6.
5x−18=−58
Add 18 to both sides of the equation.
5x=−40
Divide both sides by 5.
x=−8
The system is now solved.
x=−8,y=6
