Answer:

h = 9 but see note below.

Step-by-step explanation:

Givens

h = ?

L = h + 31

diagonal = 41

Formula

h^2 + (h+31)^2 = 41^2

h^2 + h^2 + 62h + 961 = 1681

2h^2 + 62h + 961 = 1681

2h^2 + 62h + 961 - 1681 =0

2h^2 + 62h - 720 = 0

h^2 + 31h - 360 = 0

(h - 9) ( h + 40) = 0

h + 40 has no meaning

h - 9 = 0

h = 9

I suppose you might have to answer it as 9.0

What's 2|–9| – |–2|?
A. 16
B. 20
C. -20
D. -18

Answers

Answer:

2|–9| – |–2|

= 2(+9) -( +2)

= 2(+9) - 2

= 16

Answer is option A.

Hope it helps....... plz mark as brainliest

Answer: A) 16

Working:

• First we calculate the absolute values. The absolute value for any number is always positive, therefore |-9| = 9 and |-2| = 2.
• Rewriting the question knowing these facts get us: 2 x 9 - 2
• Using the Order of Operations, we multiply first getting us 18 - 2
• Final answer is 16.

I hope this made sense please just ask if you have any more questions or need me to explain something!

For the point P(21, 24) and Q(26, 27) , find the distance d(P, Q) and the coordinates of the midpoint M of the segment PQ

Answers

Answer:

d(P,Q) = 5.83 units

Mid-point = (23.5,25.5)

Step-by-step explanation:

Given points are:

P(21,24) = (x1,y1)

Q(26,27) = (x2,y2)

The distance formula is given by:

[tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Here (x1,y1) are the coordinates of first point and (x2,y2) are coordinates of second point.

Putting the given values in the formula

[tex]d(P,Q) = \sqrt{(26-21)^2+(27-24)^2}\\= \sqrt{(5)^2+(3)^2}\\=\sqrt{25+9}\\=\sqrt{34}[/tex]

[tex]= 5.830952[/tex]

Rounding off: 5.83 units

The mid-point of two points is given by the formula:

[tex]M = (\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})[/tex]

Putting the values:

[tex]M = (\frac{21+26}{2} , \frac{24+27}{2})\\=(\frac{47}{2} , \frac{51}{2})\\=(23.5, 25.5)[/tex]

Hence,

d(P,Q) = 5.83 units

Mid-point = (23.5,25.5)

6x-10y=-8
determine if parallel

Answers

Answer: Slope = 1.200/2.000 = 0.600

 x-intercept = -4/3 = -1.33333

 y-intercept = 4/5 = 0.80000

Step-by-step explanation: 6x−10y=−8

Step 1: Add 10y to both sides.

6x−10y+10y=−8+10y

6x=10y−8

Step 2: Divide both sides by 6.

6x/6=10y-8/6

x=5/3y+-4/3

Slope = 1.200/2.000 = 0.600

 x-intercept = -4/3 = -1.33333

 y-intercept = 4/5 = 0.80000
