Y = x^2 + 8x - 3
y = x^2 + 8x + (8/2)^2 - 3 - (8/2)^2
y = x^2 + 8x + 16 - 3 - 16
Using the distributive property, a(b+ c) = ab + ac. In this case, b is 30, so the blank is 30.
15=3b
15/3 = 3b/b
5= b
Isolate the variable by diving 3 on both sides
Answer:
here you go :)
Step-by-step explanation:
Replace the variables with their corresponding values:

Cancel out 2 in both numerator and denominator.

Add 3 and 5 to get 8.

Finally, divide 8 by 5 to get your answer:

Your answer is (a) 1.6
