Answer:
137
Step-by-step explanation:
A straight line is 180 so take 180 and subtract 43

Answer: Choice C. (2x - 6i)(x + 3i)</h3>
Work Shown:
2x^2 + 18
2(x^2 + 9)
2(x - 3i)(x + 3i) .... see note below
(2x - 6i)(x + 3i)
Note: I used the rule that a^2 + b^2 = (a - bi)(a + bi). I recommend FOILing out the right hand side to confirm the equation is true. You'll use the idea that i^2 = -1.
Answer:
R'T = 28
Step-by-step explanation:
Dilation is one of the methods used in transformation. It is a process in which the size of a given object or shape is either increased or decreased by a scale factor.
In the given question, the length of RT was increased by the scale factor, so that;
R'T = RT x scale factor
= 8 x 3.5
= 28
R'T = 28
Therefore, the length of R'T is equal to 28.
