Answer:
x = 7, x = -3
Step-by-step explanation:
We can find the zeros by factoring the equation using the zero product property.
x^2-4x-21 = 0
(x-7)(x+3) = 0
<u>x-7 = 0</u>
x = 7
<u>x+3 = 0</u>
x = -3
Zeros are x=7 and x= -3.
<em>(2/3)*x = y is an example of direct variation because it can be rewritten as 2/3 = y/x where if x increases y also increases.</em>
Answer: Measure 1 is 54 degrees it is congruent to measure 3. Measure 7 is 90 degrees it is congruent to measure 5.
