What is the perimeter of the quadrilateral if the two triangles are congruent using SSS

Mathematics
1 answer:
Westkost [7]3 years ago
6 0

Answer:

20 units (I used units because that's what i was taught when there isn't a specific unit)

Step-by-step explanation:

If the triangles are congruent, that means that everything is congruent/the same. So what we do is, we set both equations equal to each other.

6x - 3 = 4x + 9

And now we simplify.

6x - 3 = 4x + 9

-4x         -4x

--------------------

2x - 3 = 9

    +3     +3

-------------------

2x = 12

÷2      ÷2

---------------

x = 6

To find the perimeter, just multiply 6 by 4 since there's four sides. 6 x 4 = 20

How much greater is the area of a a square with a side length of 8 inches than the area of a circle with radius of 4 inches?
expeople1 [14]
Area of a square= l²
                           = 8×8 = 64 in²

Area of  a circle= πr²
                         = π × 4²
                         = 50.3 in²
Difference = 64 - 50.3 = 13.7 in²

X^2+20x+c find the value of c that makes a perfect square trinomial
ollegr [7]

Answer:

This means c=100. The factored form is (x+10)^2.

Step-by-step explanation:

A perfect square is a trinomial that factors into the form (x+a)^2. To find the value of C to finish the perfect square divide 20 by 2 and square it.

20/2 = 10

10*10=100

This means c=100. The factored form is (x+10)^2.
