If this is a perfect square trinomial, factor it 2 + 5x + 25 O(x + 5)? This is not a perfect square trinomial. 0 0 (x – 5)? o (x + 5) (2 5)​

Answers

Answer:

There is one "special" factoring type that can actually be done using the usual methods ... "Perfect square trinomials" are quadratics which are the results of squaring binomials. ... This means that I'll have a "plus" sign between the x and the 5. ... it had a middle term of –25x, and this does not match what the pattern requires.

Step-by-step explanation:

2x + 5 + 4x - 1 + 2x + 5 + 4x - 1

Combine like terms.

6x + 5 - 1 + 2x + 5 + 4x + 1

8x + 5 - 1 + 5 + 4x - 1

12x + 5 - 1 + 5 - 1

Subtract 2 from 10 to get 8.

12x + 8

The perimeter of the rectangle is 12x + 8, which is B.

Find the area of the composite figure. Show your work. What is the area of the figure?​

Answers

Answer:

46 units²

Step-by-step explanation:

The figure can be decomposed into 2 triangles and a rectangle.

Area of rectangle = L*W

W = 4

L = 8

Area = 32 units²

Area of triangle 1:

Area = ½(b*h)

b = 3

h = 4

Area = ½*3*4

Area = 6 in.

Area of triangle 2:

b = 4

h = 4

Area = ½*4*4

Area = 8 units

✅Area of the figure = 32 + 6 + 8

= 46 units²

the table shows the costs of different size jars of peanut butter. Which of the jars have the lowest unit rate?

Answers

Answer:

Step-by-step explanation:

Option C) 25-oz jar has the lowest unit rate

What is the unit rate?

Unit rate is the ratio of two different units, with the denominator as 1. For example, kilometer/hour, meter/sec, miles/hour, salary/month, etc

Given here the cost of a 12 oz jar is $3

so the unit rate of a 12 oz jar is = 12/3

                                                 = 4

similarly, the unit rates of all the jars from the given table are

 18 oz jar = 18/4.40

                = $4.09

25 oz-jar = 25/6.75

               = $3.703

32 oz jar = 32/8.25

               = $3.87

Hence the jar with the lowest unit rate is the 25 oz jar

Intersecting Secant (Exterior)
Find X =

Answers

Answer: x = 13

Step-by-step explanation:    the equation to solve this is:

4 × (4 + 8) = 3 × (3 + x)

so we solve the first half of that:

4 × (4 + 8)

4 × 12

48

now we have:

48 = 3 × (3 + x)

so we switch the sides to make it easier and solve

3 × (3 + x) = 48

divide both sides by 3

3 × (3 + x) ÷ 3 = 48 ÷ 3

and get

3 + x = 16

now subtract 3 from both sides

3 + x = 16

-3         -3

and finally we get

x = 13

Find the perimeter and the area of the polygon with the given vertices N (-4,2) , P (5,2) , Q (5,5) , R (-4,5) PLEASE ANSWER

Answers

Answer:

Perimeter = 24;  Area = 27

Step-by-step explanation:

If you draw out the coordinates on paper you can clearly see side lengths be seeing how far away they are from eachother on the axis'

From Point N to point P it travels the x axis by 9 units.

Therefore the bottom side is 9 units long.

From Point N to Point R it travels the y axis by 3 units

therefore the left side length is 3 units long

Area = b*h = 9*3 = 27

Perimeter = 2b + 2h = 2*9 + 2*3 = 24

Two chords intersect within a circle to form an angle whose measure is 53 degrees. If the arcs are represented by 3x+3 and 10x-14, find the measure of the LARGER of these two arcs.

Answers

Answer:

76degrees

Step-by-step explanation:

Using the theorem which states that the vertex of the angle inside a circle is half the sum of the measured intercepted arcs. Hence;

Angle at the vertex = 53 degrees

Half the sum of intercepted arcs = 1/2(3x+3+10x-14)

Half the sum of intercepted arcs = 1/2(13x-11)

Equating to  the vertex to find x

1/2(13x-11) = 53

13x - 11 = 2 * 53

13x - 11 = 106

13x = 106 + 11

13x = 117

x = 117/13

x = 9

For the arc 3x + 3

= 3(9) + 3

= 27 + 3

= 30degrees

For the arc 10x - 14

= 10(9) - 14

= 90 - 14

= 76degrees

Hence the measure of the larger of the two arcs is 76degrees
