Draw two different figures that each have a perimeter of 14 units .Then find the aera of each

1 answer:

7 0

You could make a rectangle with the base of 5 units and a height of 2 units. So the perimeter would be 5+5+2+2 which is 14 and the area would be base times height ,in this case it would be 5 times 2 which is 10 squared units. The 2nd figure would be an isosceles triangle with the base of 6 units the height of 2 units, and the 2 other sides would be 4 units. The perimeter would be 6+4+4 which equals to 14 units and the area, 6 times 2 and the half of that is 6 so the area for the triangle is 6 units squared

Find the value of k so that the point A lies on the line given by equation.

PtichkaEL [24]

Answer:

k = 0

Step-by-step explanation:

Explanation:-

given straight line equation is k x+(k+1)y=2......(1)

The point A(2,2) lies on the equation is

substitute x = 2 and y=2

k(2) + (k+1)(2) =2

now simplify 2 k+2 k+2 = 2

subtracting '2' on both sides , we get solution is

4 k +2 -2 = 2-2

4 k =0

k = 0

Tema [17]

Answer:

14 and 16.

Step-by-step explanation:

We know that two consecutive even numbers is 30.

Let's let n be any number.

Then the first even number must be 2n.

This is because n can be any number, either even or odd. However, if we multiply it by 2, this ensures that 2n is even. Remember that any number multiplied by 2 yields an even number.

Therefore, the consecutive even number will be (2n+2). Not (2n+1), because that gives an odd number.

We know that they sum to 30. So, we can write the following equation.

$(2n)+(2n+2)=30$

And we solve from there:

$4n+2=30\\\Rightarrow4n=28\\\Rightarrow n=7$

So, the value of n is 7.

Therefore, the first even number is 7(2)=14.

And the consecutive even number is 16.
