1) The last option is your answer. It is not the same equation as the others when rearranged. 

2) 1/3(12x - 24) = 16

4x - 8 = 16
4x = 16 + 8
4x = 24
x = 6, the second option.

3) Notice they are subtracting the constant term of 5 from both sides. Since it's subtraction, your answer is the second option. 

4) 3/5(30x - 15) = 72

18x - 9 = 72 or 3(6x - 9) = 72
18x = 72 + 9
18x = 81
x = 81 / 18
x = 4.5

The 3rd, 4th, 5th, and 8th options are all that apply. 

5) 2/3(6x + 12) = - 24

4x + 8 = - 24
4x = - 24 - 8
4x = - 32
x = - 8

The 1st, 6th, and 8th options are all that apply.

Determine all values of k that make each of the following a perfect square trinomial. X^2+8x+k
-Dominant- [34]

Answer:

k can either be

12

or

−

12

.

Step-by-step explanation:

Consider the equation

0=x2+4x+4

. We can solve this by factoring as a perfect square trinomial, so

0=(x+2)2→x=−2 and−2

. Hence, there will be two identical solutions.

The discriminant of the quadratic equation (b2−4ac) can be used to determine the number and the type of solutions. Since a quadratic equations roots are in fact its x intercepts, and a perfect square trinomial will have

2 equal, or 1

distinct solution, the vertex lies on the x axis. We can set the discriminant to 0 and solve:

k2−(4×1×36)=0

k2−144=0

(k+12)(k−12)=0

k=±12

Your answer would be B: 82 inches


To find the circumference of a circle and only given the diameter, you will simply multiply the diameter by pi (3.14) and that will be your answer. You may have to round. Hope this helps!
