My recommendation would be to factor..
x² + 4x + 3 = 0 factor the left side into two binomials
(x + 3)(x + 1) = 0 set each of these binomials equal to zero and solve
x + 3 = 0 Implies x = -3
x + 1 = 0 implies x = -1
18 = .75x
/.75 /.75 (divide both sides by .75 to isolate x)
24 = x
24 total students
Hope this helps!
Answer:

which agrees with the first answer in the list of possible options.
Step-by-step explanation:
We can use the fact that the addition of all four internal angles of a quadrilateral must render
. Then we can create the following equation and solve for the unknown "h":

Therefore the angles of this quadrilateral are:

Answer:
28 beads were used to make the bracelet. 7 beads were not yellow.
Step-by-step explanation:
3/4 beads used to make the bracelet are yellow

1/3 of the 21 beads would be 1/4 of the bracelet
7 beads are 1/3 of 21 beads
7 × 4 = 28 beads
