For this item, I assume that Svetlana's hair is 4 cm long and she wanted it to be at least 7 cm long.
We let x be the number of months it will take for her hair to be 7 cm long. The sum of the product of x and the rate and the initial length should be at least 7. Mathematically,
1.51x + 4 ≤ 7
[Sum of X coordinates/3, sum of Y coordinates/3] of sides of a triangle
Top second one under grass and across from minor 77.972.
<span>5(x + 7) = 5(x) + 5(7) = 5x + 35</span>
B = {a, b, c, d}
C = {0, a, 2, b}
B ∪ C = {a, b, c, d, 0, 2}
<h3>Answer: E)</h3>
Everything from the set B and everything from the set C give to one set. Duplicated elements are written only once.
