Answer:

41

Step-by-step explanation:

(5x - 2)² = ax² - bx + c

25x² - 20x + 4 = ax² - bx + c

a = 25

c = 4

a + c²

25 + 4²

25 + 16

Answer:

41

Step-by-step explanation:

(5x-2) ^2 = ax^2 -bx +c

Foil

(5x-2) (5x-2)

25x^2 -10x -10x +4

25x^2 -20x+4

a=25 b=20 c = 4

a+c^2 =25 +4^2 =25+16 = 41

If they are parallel then the coefficients of x and y will remain the same.  Only the constant will change.

2x + 3y = ?
2(-2) +3(3) = -4 + 9 = 5 so ? is 5

ANSWER: 2x + 3y = 5

The circumference of the flotation device above is 62.8 inches . If three flotation devices are lined up end-to-end , then what
Karo-lina-s [1.5K]

Answer: 60 in

Step-by-step explanation:

Hi, to answer this question, first we have to calculate the diameter of one flotation device:

Circumference of a circle C = (3.14) (diameter)

Replacing with the values given:

62.8 =3.14 d

Solving for d (diameter)

62.8 /3.14 =d

20in = d

Now, since the three flotation devices are identical, we simply have to multiply the diameter of one device by 3 , to obtain length of the flotation devices lined up.

20x3 =60 in

Four points which lie at (0,0) ; (0,2) ; (2,2) ; (2,0)

\large \green{ \underline{ \blue{ \boxed{\bf{ \red{To \: Find-}}}}}}

What is the figure formed?What is the area of the figure?

\large \green{ \underline{ \blue{ \boxed{\bf{ \red{Solution-}}}}}}

The given points lie on graph as per the order given in the attachment.

Which shape?

As the points lie 2 units apart from their adjacent sides. It can be a square or rhombus.

The opposite pairs of sides are also parallel to each other. The adjacent sides of the figure formed are also perpendicular to each other.

<u>Hence! the figure formed is a square.</u>

What is the area?

\large{\sf{ \longmapsto Area_{(square)} = s \times s}}

\large{\sf{ \longmapsto Area_{(square)} = {s}^{2} }}

\large{\sf{ \longmapsto Area_{(square)} = {(2)}^{2} }}

\large{\sf{ \longmapsto Area_{(square)} = 4 \: sq. \: units}}
