the congruent sides of an isosceles triangle are each one unit longer than the length of the shortest side of the triangle the p
vazorg [7]

Let s represent the short side of the triangle. The long sides of the triangle are each s+1, and the triangle's perimeter is

... s + (s+1) + (s+1) = 3s+2

The length of one side of the square is s-2, and its perimeter is 4 times that, 4(s-2) = 4s-8. The square and triangle have the same perimeter, so

... 3s+2 = 4s-8

... 10 = s . . . . . . . . add 8-3s to both sides

The length of the shorter side of the triange is 10 units.

The circumference of a circle can be found using the formula C=2*3.14r
alexdok [17]

C=2πr

C=πd

A=πr^2

r=C/2π

r=1/2 d

<u>By the way all you do to solve r is: </u>

C=2πr

C/2π=2πr/2π

C/2π=r

r=C/2π

Hope this helps:)

Is the gcf of a pair of numbers ever equal to one of the numbers
Dvinal [7]
It depends. For example the GCF of 4 &2 is 4, so in a sense yes. With other numbers (such as odds) that is not always the case :D

Please help I’m very confused
Drupady [299]

Answer:

147

Step-by-step explanation:

The ∑ symbol means sum the term inside 4n + 1 from n = 2 to n = 8

Substitute n = 2, 3, 4, 5, 6, 7, 8 into the expression and sum the results , that is

4(2) + 1 + 4(3) + 1 + 4(4) + 1 + 4(5) + 1 + 4(6) + 1 + 4(7) + 1 + 4(8) + 1

= 9 + 13 + 17 + 21 + 25 + 29 + 33

= 147
