Answer:
B) BC'= 8, m A'= 28°
Step-by-step explanation:
When dilating a figure, it increases its size or decreases. In this case, as it is dilating by a factor of 1/2, you can assume it decreases.
To find the value of the new figure, A'B'C', you have to multiply the factor times the lengths of the triangle, or, the only one they are asking for in this case, the length BC':
- BC' = BC×1/2
- BC' = 16×1/2
- BC' = 8
The angles, otherwise, do not change. When figures are dilated, they are similar. The properties of similar figures are that they have congruent angles, therefore, the same angles. They do not have any effect caused by the factor, so m A' stays at 28°.
Answer:
3x2+9x+3y
Step-by-step explanation:
Let's simplify step-by-step.
17x+3x2+2y+y−5x−3x
=17x+3x2+2y+y+−5x+−3x
Combine Like Terms:
=17x+3x2+2y+y+−5x+−3x
=(3x2)+(17x+−5x+−3x)+(2y+y)
Answer:
15 meters and 25 meters long
Step-by-step explanation:
<em>There are 2 pieces of rope</em>.
Total length of both---> 40 meters
Length of piece 1 ------> x
Length of piece 2 -----> x + 10
<em>Find the value of x.</em>
<em>Form an equation ----> Length of piece 1 + length of piece 2 = total length</em>
x + (x + 10) = 40
2x + 10 = 40
2x = 30
x = 15
Length of piece 1 --> x ---> 15
Length of piece 2 --> x + 10 ----> 15 + 10 = 25
Therefore, one piece is 15 meters long and the other piece is 25 meters long.
