If you locate the points on the graph, 1 and 4 are not in the shaded and 2 and 3 are, which means they are not solutions.
Answer:
10 = b
Step-by-step explanation:
Begin by expanding (x + 5)^2
(x + 5)(x + 5)
First: x*x = x^2
Outside: x * 5 (the last term which is a 5)
Inside: 5+ x
Last: 5*5 = 25
x^2 + 5x + 5x + 25
x^3 + 10x + 25
Ok so... Let x be 2.1
x = 2.1 / (3/10)
multiply both the numerator and denominator by 10 which gives
x = 21/3 SO the answer is......
x = 7 Yay!!! Have a god day
