Answer:

If the circle is inside the square the area of the square is 144

Step-by-step explanation:

The diameter of a circle is equal to the side length of a square.

So $d = 2r$ the diameter of the circle is 2(6)=12

so one side length of the equals 12

Area of square = $s^{2}$ $12^{2} = 144$

Answer:

12. (x, D, E, F) = (8, 38°, 75°, 67°)

13. (x, P, Q, R) = (13, 126°, 30°, 24°)

Step-by-step explanation:

The sum of angles in a triangle is 180°. We choose to write the equations assuming all measures are degrees.

12. (5x -2) +(9x +3) +(11x -21) = 180

25x = 200 . . . . . . . add 20, simplify

x = 8 . . . . . . . . . divide by 25

Then the angle measures are ...

∠D = 5(8) -2 = 38°

∠E = 9(8) +3 = 75°

∠F = 11(8) -21 = 67°

13. (10x -4) +(4x -22) +(x +11) = 180

15x = 195 . . . . . . . . . . add 15, simplify

x = 13 . . . . . . . . . divide by 15

Then the angle measures are ...

∠P = 10(13) -4 = 126°

∠Q = 4(13) -22 = 30°

∠R = 13 +11 = 24°

3x + 2 ≤ 14 -5 + 2x > 15 * -2x + 4 ≥ 18 HaLp i don't gets

Answer:

x ≤ 4
x > 10
x ≤ -7

Step-by-step explanation:

We're guessing you want to solve for x in each case. You do this in basically the same way you would solve an equation.

1. 3x +2 ≤ 14

3x ≤ 12 . . . . . subtract 2

x ≤ 4 . . . . . . . divide by 3

2. -5 +2x > 15

2x > 20 . . . . . . add 5

x > 10 . . . . . . . . divide by 2

3. -2x +4 ≥ 18

4 ≥ 18 +2x . . . . . add 2x

-14 ≥ 2x . . . . . . . subtract 18

-7 ≥ x . . . . . . . . . divide by 2

Additional comment

The statement above that the same methods for solving apply to both equations and inequalities has an exception. The exception is that some operations reverse the order of numbers, so make the inequality symbol reverse. The usual operations we're concerned with are multiplication and division by a negative number: -2 < -1; 2 > 1, for example. There are other such operations, but they tend to be used more rarely for inequalities.

You will note that we avoided division by -2 in the solution of the third inequality by adding 2x to both sides, effectively giving the variable term a positive coefficient. You will notice that also changes its relation to the inequality symbol, just as if we had left the term where it was and reversed the symbol: -2x ≥ 14 ⇔ -14 ≥ 2x ⇔ x ≤ -7 ⇔ -7 ≥ x

A line is defined by the equation 2x+y -4. Which shows the graph of this line?

Nitella [24]

Answer:

Not sure if you mean 2x+y=-4 or 2x+y=4

either way put it in y=mx + b form (slope intercept)

Step-by-step explanation:

so for 2x+y = -4 first move everything away from the side with "y" by -2x from each side you get y= -2x+ -4 so m= -2/1 (slope) and b= -4 the place the line crosses the y axis

so for 2x+y = 4 first move everything away from the side with "y" by -2x from each side you get y= -2x+ 4 so m= -2/1 (slope) and b= 4 the place the line crosses the y axis
