(2x-5)(x+4)=0

2x-5=0, x+4=0

2x=0+5,

2x=5,

x=5/2,

x+4=0

x=0-4=-4

Answer:

Yes

Step-by-step explanation:

The only quadrilaterals with congruent diagonals are squares and rectangles and squares are technically rectangles so the answer is yes.

If the diagonals of a quadrilateral are congruent. Then the quadrilateral is always a rectangle which is false.

The quadrilateral has four sides and four angles. The sum of internal angles is 360 degrees.

It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.

If the diagonals of a quadrilateral are congruent. Then the quadrilateral can be a square or a rectangle.

If the diagonals of a quadrilateral are congruent. Then the quadrilateral is always a rectangle which is false.

Answer:

1/7

Step-by-step explanation:

Given that :

Line AB contains points A (8, −4) and B (1, −5)

Slope = Rise / Run

Rise = y2 - y1 = - 5 - (-4) = - 5 + 4 = - 1

Run = x2 - x1 = 1 - 8 = - 7

Slope = Rise / Run = - 1 / - 7

Slope = 1/7

Answer:

A) x + 0

Step-by-step explanation:

In triangle ABC, the coordinates are: A(1, -1), B(1, -5) and C(4, -5)

In triangle A'B'C', the coordinates are: A(1, -5), B(1, 1) and C(4, 1)

Look at the x-coordinates in both the triangles remains the same because the triangles are reflected over x-axis, therefore, only the y-coordinate changes.

Therefore, the rule for x-coordinates = x + 0

Answer: A) x + 0

Answer:

(A).option is correct..54cm2

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

we can find angle C  b/c the angles of a triangle always add to 180 , soo

180= C + 81 +63.5

35.5 = C

now that we have angle C and we know the Hyp we can use sin to find side g

where g = Opp and Hpy = 13.8 for this question

Sin(35.5) = Opp / 13.8

13.8*Sin(35.5) = Opp

8.0137 = Opp

g = 8.0137

next they ask for the area of the biggest triangle  ABC ( there are two smaller ones when you use D )

we can use 1/2 * base * height , but we don't know the base yet, even thou we do know the height.  

we can solve for line segment CD and DB and then add them for the side a .. or the base of the biggest triangle sooo.. CD = adj

Cos(35.5) = Adj / 13.8

13.8*Cos(35.5) = Adj

11.234794 =Adj

now solve for DB using cos again but with the other smaller triangle where  Adj = DB now

Cos(63.5) = Adj / 8.9

8.9*Cos(63.5) = Adj

3.971160

add these two Adjs together to get the total  'a' side

15.205954

now plug in side a as the base and g as the height of our biggest triangle

Area = 1/2 * 15.205954 * 8.0137

Area = 60.9159

rounded to 2 sig figs

Area = 60.92   :)   hope you get an "A"    :P

Answer:

16

Step-by-step explanation:

The formula for finding the length of a side of a right triangle is:

A^2 + B^2 = C^2 (c being the hypotenuse.)

We know what the length of the hypotenuse and one of the legs is, so we can solve by taking B^2 (the leg measuring 12) and subtracting it from C^2 (the hypotenuse) and then finding the square root of C^2.

20^2 - 12^2 = 256

or in simpler terms

20^2 - 144 = 256

Then, if we find the square root of 256 we get 16. We can check our work by substituting it back into the equation

16^2 + 12^2 = 20^2

or in simpler terms

256 + 144 = 400

So the length of the missing leg is 16. I hope this helps :)

Answer:

C. 16

Step-by-step explanation:

In order to find one side of a right triangle, given two sides, you can use the Pythagorean theorem: [tex]A^2+B^2=C^2[/tex]

We already have the values of one of the bases (12) and the hypotenuse (20), so we are looking for the second base. So, we have the values of B and C, and we need to find A.

To find A, put the values you already have into the formula as follows:

[tex]A^2+12^2=20^2[/tex]

Next, square each value:

[tex]A^2+144=400[/tex]

Subtract 144 from 400 to simplify the equation.

[tex]A^2=256[/tex]

And finally, find the square root of 256 to find A.

[tex]A=16[/tex]

Final answer:

C. 16
