Answer:
x = 28
Step-by-step explanation:
The ratios of corresponding sides are equal, that is
= 
( cross- multiply )
8(x - 7) = 168 ( divide both sides by 8 )
x - 7 = 21 ( add 7 to both sides )
x = 28
Answer:
1.5 + 1x
Step-by-step explanation:
8.25 - .25x = 9.75 - .75x
First, add .25 to each side.
8.25 = 9.75 + 1x
Next, subtract 8.25 from 9.75
1.5 + 1x (simplified)

Triangle
Square or
rectangle?
Two figures that can be transformed into each other by a congruence transformation are said to be congruent. Cougruence transfomations of the plane include translation, rotation, reflection, glides, and the identity map. Every congruent transformation in the plane can be achieved by a maximum of three reflections
