Work out the perimeter of this isosceles triangle.
all of the sides are in cm.

38 cm.

Step-by-step explanation:

Two sides are equal ( as its an isosceles triangle). so:

3x - 5 = 19 - x

3x + x = 19 + 5

4x = 24

x = 6.

So the perimeter

=  3x - 5 + 19 - x + 2x

= 3(6) - 5 + 19 - 6 + 2(6)

= 18 - 5 + 19 - 6 + 12

= 49 - 11

= 38 cm.

the image of (6, 9) under a dilation is (4, 6). the scale factor is

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000
