Answer:

"2 + 2(-3)(7) = negative

-2(27 ÷ 9)+4= negative

(14 ÷ -2)(-6)= positive

(4 - 10) - ( 8 ÷ ( -2))= negative

Step-by-step explanation:

2 + 2(-3)(7) = -40

-2(27 ÷ 9)+4= -2

OLga [1]

Answer:

9.     6k + 5 and 2k - 1.

10.    5√2 .

Step-by-step explanation:

9.    Area = 12k^2 + 4k - 5

Factoring:

12k^2 - 6k + 10k - 5

= 6k(2k - 1) + 5(2k - 1)

= (6k + 5)(2k - 1)

So the required lengths are 6k + 5 and 2k - 1.

10.  The ratio of a leg to the hypotenuse is  1: √2 so if the hypotenus = 10 the length of a leg is 10 / √2  

= 10 √2  / 2

= 5√2 .

X^2+y^2 +4x−6y+9=0<br> what is the center and the radius
mojhsa [17]

Answer: Center (-2,3), radius 2

Step-by-step explanation: Subtract 9 from both sides, then complete the square for the x and y variables & add to both sides: x^2+4x+4+y^2-6y+9=-9+4+9 = (x+2)^2+(y-3)^2=4. The center of this circle in the form (x-a)^2+(y-b)^2=r^2 is (a,b) with radius r. a=-2, b=3, r=\sqrt{4}=2

Type the correct answer in each box. Use numerals instead of words. The domain of this function is {-12, -6, 3, 15}. Complete th
Ira Lisetskai [31]

The complete table is

x -12 -6 3 15

y -6 5 15 15

<h3>How to complete the table?</h3>

The domain is given as:

Domain = {-12, -6, 3, 15}.

The incomplete table is given as

x

y -6 5 15 15

Enter the domain in the x values

x -12 -6 3 15

y -6 5 15 15

Hence, the complete table is

x -12 -6 3 15

y -6 5 15 15
