Prove that (x+y)(x-y)+(y+z)(y-z)+(z+x)(z-x)=0

Answer:x=52

Step-by-step explanation:as SRQ is a right triangle,

<SQR=180°-(90+34)°

=56°

again, < SQR+<SQP=180°

< SQP=124

x+72°=124

x=52°

Answer:

x=52

Step-by-step explanation:

the answer is x=52.

Answer:

An equation for the parabola would be y²=-19x.

Since we have x=4.75 for the directrix, this tells us that the parabola's axis of symmetry runs parallel to the x-axis.  This means we will use the standard form

(y-k)²=4p(x-h), where (h, k) is the vertex, (h+p, k) is the focus and x=h-p is the directrix.

Beginning with the directrix:

x=h-p=4.75

h-p=4.75

Since the vertex is at (0, 0), this means h=0 and k=0:

0-p=4.75

-p=4.75

p=-4.75

Substituting this into the standard form as well as our values for h and k we have:

(y-0)²=4(-4.75)(x-0)

y²=-19x

Answer:

6x - 11 + 7x - 27 = 36

6x + 7x = 13x

-11 + (-27) = -38

13x - 38 = 36

-38 - 36 = -74

13x/13 = -74/13

x = -74/13

Answer:

72 / 2 = 36

Step-by-step explanation:

Look at 7 first and figure out how many times 2 will go into 7. 2 will only go into 7 three times. (2 x 3= 6) So put 3 at the top of your division problem and subtract 6 from 7. You should get 1. Then, bring down your 2 to make that one a 12. How many times will 2 go into 12? 6 times. 6 x 2 equals 12 so put 6 at the top of your division problem next to that 3. Subtract your 12 from 12 to get 0. Your final answer would be 36.

Hope this helped!

The division of 72 and 2 is 36.

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

The given numbers are 72 and 2.

72 divided by 2

Here, 72/2

Where, 72 is dividend and 2 is divisor.

72/2 = 36

So, quotient is 36

Therefore, the division of 72 and 2 is 36.

Slope is -2

The Y-intercept is (3,0)

The equation Is y=-2(x-3)

Step-by-step explanation:

Don't use my answer right away but when someone else answers you can compare to figure out which one is right.

Answer: The slope is 1/2.

The y-intercept is point (0,3)

The equation of the line in slope-intercept form is y = 1/2x + 3.

Answer:

y = -2x + 17

Step-by-step explanation:

The line is parallel to 4x + 2y = 10, and parallel lines have the same slope. Let's convert this line into slope intercept form:

2y = 10 - 4x,

y = -2x + 5

So the slope of this line and our line [the line which we want to determine in slope intercept form] is -2

Given the point (7, 3) and slope -2 we can solve for the y-intercept;

y = mx + b,

3 = -2(7) + b,

-14 + b = 3,

b = 17

Your solution is y = -2x + 17 (First option)

Answer:

15 miles

Step-by-step explanation:

It is given that,

Shane could drive due north to get to his parents' house or he could drive due east to get to his grandparents' house.

It is 8 miles from Shane's house to his parents' house and a straight-line distance of 17 miles from his parents' house to his grandparents' house.

It can be calculated by considering a right angled triangle. Using pythagoras theorem, we can find the distance between Shane from his grandparents' house. Let it is d.

[tex]d^2=\sqrt{17^2-8^2} \\\\=15\ \text{miles}[/tex]

Hence, Shane is 15 miles from his grandparents' house.

Answer:

A

Step-by-step explanation:

Let T represent the total number of turtle nests found during the season.

The 28 turtle nests was 40% of 0.4 of the total. Therefore:

[tex]28=0.4T[/tex]

So, to find T, divide both sides by 0.4:

[tex]T=70[/tex]

So, the total number of turtle nests the group found during tthe season was 70.

Hence, our answer is A.
