After the scale factor is applied to the dimensions of the rectangle shown, choose all that correctly give the new dimension. (Check all that are true)

A) New width after a scale factor of 3.
12 cm

B) New length after a scale factor of 4.
80 cm

C) New perimeter after a scale factor of 2.
112 cm

D) New area after a scale factor of 2.
160 cm²

Statements in option A and D are true

Step-by-step explanation:

Step 1 :

Length of the given rectangle = 10 cm

Width of the given rectangle = 4 cm

Step 2 :

A)

Apply scale factor of 3

New width is 4 * 3 = 12 cm

Hence the statement in option A is true

Step 3 :

B)

Scale factor = 4

New length is 10 * 4 = 40 cm

Hence option B is false

Step 4 :

C)

Scale factor = 2

New length is 10 * 2 = 20 cm

New width is 4 * 2 = 8 cm

New perimeter is 20+20+8+8 = 56 cm

Hence option C is false

Step 5 :

D)

Scale factor = 2

New length is 10 * 2 = 20 cm

New width is 4 * 2 = 8 cm

New area is 20*8 = 160 sq cm

Hence option D is true

(-1,0) and (4,0) are x-intercepts.

step-by-step explanation:

x-intercepts are all points on the x-axis.

points (-1,0) and (4,0) are both x -intercepts.
