Which of the following constants can be added to x^2 + 2/3x to form a perfect square trinomial?

Angelina_Jolie [31]

Hello.

A trinomial is a perfect square if the square root of the first term times the square root of the third term times 2 equals the middle term.

$\boxed{\mathsf{x^{2} + \dfrac{2}{3} x}}$

a) Adding 1/9:

$\cdot \: \mathsf{x^{2} + \dfrac{2}{3} x + \dfrac{1}{9}} \\ \\ \\ \mathsf{\sqrt{x^{2}} \times \sqrt{\dfrac{1}{9}} \times 2 =} \\ \\ \\ \mathsf{x \times \dfrac{1}{3} \times 2 =} \\ \\ \\ \mathsf{\dfrac{2}{3} x \rightarrow it \: is \: a \: perfect \: square \: trinomial}$

b) Adding 4/9:

$\cdot \: \mathsf{x^{2} + \dfrac{2}{3} x + \dfrac{4}{9}} \\ \\ \\ \mathsf{\sqrt{x^{2}} \times \sqrt{\dfrac{4}{9}} \times 2 =} \\ \\ \\ \mathsf{x \times \dfrac{2}{3} \times 2 =} \\ \\ \\ \mathsf{\dfrac{4}{3} x \rightarrow it \: is \: not \: a \: perfect \: square \: trinomial}$

c) Adding 4 and 1/9:

$\cdot \: \mathsf{x^{2} + \dfrac{2}{3} x + \dfrac{1}{9} + 4 = x^{2} + \dfrac{2}{3} x + \dfrac{37}{9}} \\ \\ \\ \mathsf{\sqrt{x^{2}} \times \sqrt{\dfrac{37}{9}} \times 2 =} \\ \\ \\ \mathsf{x \times \dfrac{\sqrt{37}}{3} \times 2 =} \\ \\ \\ \mathsf{\dfrac{2\sqrt{37}}{3} x \rightarrow it \: is \: not \: a \: perfect \: square \: trinomial}$

Hope I helped.

Need help with this one

kkurt [141]

So 4a=0.24 well its simple
your gonna divide 4 on both sides the 4 crosses out and 0.24 divided by 4 equals 0.06 or just .06 does that make sense?

If a rectangle has a perimeter of 56 inches and a width of 8 inches,what is the area

Alika [10]

Answer:

160 inches

Step-by-step explanation:

Area = L times W

In a rectangle, there are 4 sides

2 are width

2 are length

56 is total

8 + 8 = 16

56 - 16 = 40

40 is what is left for the 2 length sides

since there are 2 sides and they need to be equal, we divided 40 by 2

40 / 2 = 20

the length of one side is 20

area = 8 times 20

a = 160 inches

workers have painted 920 square feet of an office they have completed 80% of their job how many square feet do they need to. pai

Sloan [31]

80% = 0.80

divide the area done by the percentage:

920/0.80 = 1150

total area is 1150 square feet
