Answer:
ABC dilated
Step-by-step explanation:
Given
Triangles ABC and DEF
Required
Determine the scale of dilation
First, we pick a side on ABC
Pick a corresponding side on DEF
The scale factor is then calculated as:
i.e. ABC was dilated by 1/2
Answer:
Associative property
Step-by-step explanation:
Associative property allows you to put parenthesis in a part of the equation. We can only apply associative property on a part with multiplication or addition. If you do it with at an equation with subtraction or division you can change the result and make calculation mistake.
In this question, all of the operation used is multiplication. The result won't change even if you put parenthesis, both will give result of 480

anything 2 ask please pm me
Step-by-step explanation:
−4x+5−13x+39=180
Step 1: Simplify both sides of the equation.
−4x+5−13x+39=180
−4x+5+−13x+39=180
(−4x+−13x)+(5+39)=180(Combine Like Terms)
−17x+44=180
−17x+44=180
Step 2: Subtract 44 from both sides.
−17x+44−44=180−44
−17x=136
Step 3: Divide both sides by -17.−17x
−17
=
136
−17
x=−8
Answer:
x=−8
