The answer is A
Step-by-step explanation:
y=1.3(5) + 10 = 16.5 ---> True
y=1.3( 10) + 10 = 23 ----> True
y=1.3(15) + 10 = 29.5 ----> True
y=1.3(20) + 10 = 36 ----> True
To determine the expression that is equivalent to 8a + 20, all you have to do is find the common denominator and divide the values by it.
8a + 20
8a/4 + 20/4
4(2a + 5).
The correct solution would cue the second option - 4(2a + 5).
