Answer:
=3±√5
Step-by-step explanation:
First you distrbut the 5 which would give you
then you distribut the 3
then you solve for x
5x-30=3x-15
5x=3x-45
2x=45
x=22.5
Q.1A.). Tim has a scale model of an airplane which says it is in a 1:15 ratio what shoes that mean? Answer: It means that the scale model of the Airplane; Tim has is 15 times smaller than it's real size.
Q.2B.). If a scale factor is LESS than one, then the object will scale REDUCTION or WRITTEN as a FRACTION; bigger to smaller dimensions.
Q.3C.). If a scale factor is GREATER than one, then the object will scale A SKETCH; to larger dimensions.
Summary: A scale factor describes how much larger; or smaller; The enlarged shape is compared to the original shape.
• A description of a dilation includes the scale factor (or ratio) and the center of the dilation.
• The center of dilation is a fixed point in the plane.
• If the scale factor is greater than 1, the image is an enlargement (a stretch).
• If the scale factor is between 0 and 1, the image is a reduction (a shrink).
• If the scale factor is 1, the figure and the image are congruent.
Hope that helps you, and that is what you are looking for: : )
