7.2 and 7.3 and I honestly just did guess and check
Answer:
Equation of line: y=3x-18
Step-by-step explanation:
Point: (4,-6) and slope = 3

y=3x-18
2x^3(x+7)(x-7)
Thats the answer for your question!
Answer:
see explanation
Step-by-step explanation:
Since the 2 figures are similar then the ratios of corresponding sides are equal, that is
=
( cross- multiply )
18x = 48 ( divide both sides by 18 )
x =
=
= 2 
Similarly
=
( cross- multiply )
18y = 30 ( divide both sides by 18 )
y =
=
= 1
