The scale factor of the dilation is 1 because the image and pre-image share the SAME everything (lengths, area, etc.). So if you multiply one of the image’s length by any number other than one, the pre-image will change.
I agree because when you multiply a positive number such as 1/10 by any negative number the result will always be negative.
Answer:
D: 19 should have been subtracted from, not added to, both sides of the equation.
Step-by-step explanation:
Because if we subtract 19 from both sides, we directly get the value of x.
Equation:-
x + 19 = 34
Subtracting 19 from both sides,
=> x + 19 - 19 = 34 - 19
=> x = 15
Answer:
2
Step-by-step explanation:
all you have to do is add up all the sides and your answer will be 21 cm
