Answer:

Perimeter of Δ ABC = 7 + 8 + 9 = 24 cm

Step-by-step explanation:

In triangle Δ XYZ ,

A is the mid point of XY

B is the midpoint of YZ

C is the mid point of XZ

AY = 7

BZ =8

XZ = 18

The mid - point theorem states that,

The segment formed by connecting two mid - points of a triangle is parallel to the third side and half as long

AY = 7 then BC = 7 cm

BZ = 8 then AC = 8 cm

XY = 18 then AB = 9 cm

Perimeter of Δ ABC = 7 + 8 + 9 = 24 cm

1. What is are the coordinates of Q’ and R’ ?

Bogdan [553]

Q' = (7, 2 ) and R' = (1, - 5 )

given P(- 4, 4 ) and P'(3, 1 ), then the translation vector is

v = < 3, 1 > - < - 4, 4 > = < 7, - 3 >

Thus to obtain the coordinates of the images, add 7 to the x-coordinate and subtract 3 from the y-coordinate

Q(0, 5 ) → Q'(0 + 7, 5 - 3 ) → Q'(7, 2 )

R(- 6, - 2 ) → R'(- 6 + 7, - 2 - 3 ) → R'(1, - 5 )

2(x+1)^2 +4(x+1)+7 as a simplified polynomial

weeeeeb [17]

Answer:

2x^2+8x+15

Step-by-step explanation:

${2(x + 1)}^{2} + 4(x + 1) + 7$

$2({x}^{2} + 2x + 1) + 4x + 4 + 7$

$2 {x}^{2} + 4x + 2 + 4x + 13$

$2 {x}^{2} + 8x + 15$
