Answer:
Solutions are real and distinct
b = -1/2, -3/2
Step-by-step explanation:
4b² + 8b + 7 = 4
4b² + 8b + 3 = 0
B²-4AC = 8² - 4(4)(3) = 16 > 0
So, the solutions are real and distinct
4b² + 8b + 3 = 0
4b² + 6b + 2b + 3 = 0
2b(2b + 3) + 1(2b + 3) = 0
(2b + 3)(2b + 1) = 0
2b + 3 = 0 b = -3/2
2b + 1 = 0 b = -1/2
It’ll be the one on the far right last one ;)

Answer:
</h2>
20 x + 500 y cents
<h2>
Step-by-step explanation:
</h2>
20 x cents already given in question
