Answer:
what ever sides are multiply the points by 2 each (x time 2, y times 2) Best I got. Hope this helps some
Step-by-step explanation:
figure out the sides then:
Ex. Perform a Dilation of 4 on point A (2, 3) which you can see in the picture below. Multiply the coordinates of the original point (2, 3), called the image, by 4. Image's coordinates = (2 * 4, 3 * 4) to get the coordinates of the image (8, 12).
Since this is the area x 2, multiply 84x2
Pythagoras' theorem:
b^2 = c^2 - a^2
Substitute in the values:
b^2 = 13^2 - 12^2
b^2 = 25
Square root it
b = 5km
The answer is option B. 5km
B 3/7 because 15 divided by 5 = 3 and 35 divided by 5 = 7
x+142 =3x+64
subtract x from each side
142 = 2x+64
subtract 64 from each side
142-64 = 2x
78=2x
divide by 2
78/2 = x
x=39
The number is 39
