What two numbers have a sum of -7 and a difference of 14?
Ksivusya [100]

Answer:

The sum of two numbers is 14 and their difference is 10

Step-by-step explanation:

"2 numbers (x and y)

x+y = 14

and x-y + 10

If you each equation by positive 2, one gets 2x+2y = 28 and 2x-2y = 20

The 'y-terms' cancel out or equal zero when adding, so 4x = 48, divide by 4 on each side and x or the first number equals 12.

Plug 12 back into the equation for 'x' and subtract 12 on both sides so that y=2

The difference of 12-2=10 and the addition of 12 and 2 equals 14"

hopes this helps

He coordinates of the vertices of a polygon are (−2, −2) , (−2, 3) , (2, 4) , (3, 1) , and (0, −2) .
Nitella [24]

Answer: The perimeter is 17.52


Step-by-step explanation:

1. You can plot the points, as you can see in the graph attached.

2. As you can see in the graph, the points are:

A(-2,-2)\\B(-2,3)\\C(2,4)\\D(3,1)\\E(0,-2)

And the lenghts <em>AB</em> and <em>EA</em> are:

AB=5

EA=2

3. To find the other lenghts, you can apply the formula for calculate the distance between two points:

distance=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}

4. Thefore, you have:

BC=\sqrt{(2-(-2))^{2}+(4-3)^{2}}=4.12\\CD=\sqrt{(2-3)^{2}+(4-1)^{2}}=3.16\\DE=\sqrt{(3-0)^{2}+(1-(-2))^{2}}=4.24

5. The perimeter is:

P=AB+CD+DE+EA\\P=5+4.12+3.16+4.24+2\\P=17.52

Nick and June win some money and share it in the ratio 5:3. Nick gets £26 more than June. How much did June get?
inysia [295]

The difference between the ratio 5:3 is 2 ( 5-3 = 2)

Nick gets 2 extra shares which is equal to £26

1 share = 26 / 2 = 13

June gets 3 shares: 3 x 13 = £39
