Congruent means that they are identical
 looking at the order of the letters in the triangles EF are the last 2 and QR are the last 2
 so EF should equal QR

we are told QR = 10 so EF needs to equal 10
 so we have 6y+4 = 10

now solve for Y

6y +4 = 10
 subtract 4 from each side:
6y = 6
 divide each side by 6
y = 1

The perimeters of the triangles shown below are equal
Naya [18.7K]

Answer:

x=19

Step-by-step explanation:

The perimeter of the right triangle is

P=9+12+15 =36

The perimeter of the left triangle is

P =x-7+ x-7+ x-7 = 3x-21

Set them equal

36 = 3x-21

Add 21 to each side

36+21 = 3x-21+21

57 = 3x

Divide each side by 3

57/3 = 3x/3

19 =x

An auditorium has 30 rows of seats. The first row has 20 seats, the second row has 22 seats, the third row has 24 seats, and so
gayaneshka [121]
An = a1 + (n-1)*d
n = term to find = 30
a1 = first term = 20
d = common difference = 2

a30 = 20 + (30 - 1) * 2
a30 = 20 + 29 * 2
a30 = 20 + 58
a30 = 78

sn = (n (a1 + a30)) / 2
s30 = (30(20 + 78) / 2
s30 = (30(98) / 2
s30 = 2940/2
s30 = 1470 <===
