Answer:
Step-by-step explanation:
<u>Given formula:</u>
<u>Solving for n:</u>
- S = 180(n - 2) ⇒ open parenthesis
- S = 180n - 360 ⇒ isolate n
- 180n = S + 360 ⇒ divide both sides by 180
- n = (S + 360)/180
Answer:
A: (-3,4) (-3,6) (-5,6) (-7,4)
B: The transformation would be described as a reflection over the y axis
C: The transformation does result in a congruent figure because the shape doesn't change in size or shape and in length or width
Step-by-step explanation:
So our plots from the figure are: (3,4) (3,6) (5,6) (7,4)
So using the rule (x, y) → (-x, y) are new points would be:
(-3,4)
(-3,6)
(-5,6)
(-7,4)
This rule (x, y) → (-x, y) is used for the type of transformation that is a reflection but over the y axis.
Answer:
238 cm
Step-by-step explanation:
so we have a scale factor of 17: 1
originally we had the dimensions: 3cm by 4m
now we have 3*17 by 4*17 = 51 cm by 68 cm
Perimeter = 2*51 + 2*68 = 238 cm
When we bring 6y from right side to left side it’s sign get changed and 8y-6y=2y.
Tom would get £28.80
Sally would get £31.40
The difference is £2.60
