Thank you once again.</p>
<p>if you write them down, i could help you.</p>
<p>1.3.5. Understand the Venn Diagram: 9 students studied only butterflies; 3 students studied both (belongs to both circles); 15 students studied only grasshoppers; 3 students studied neither (outside both circles). Since there are a total of 30 science students (given), we find that 9 out of 30 = 3 / 10 = 30 % of the students studied butterflies only.</p>
<p>1.7.15. Let the intersection of AD and BE be X for convenience. The perimeter shown in bold can be found by adding the perimeter of triangle ADF and triangle BCE and subtracting the length of two dotted lines and DE, or the perimeter of XDE. Knowing that CE = 20, DF = 20, and DE = 10, we find that the perimeter of the three equilateral triangles BCE, ADF, and XDE are three times those lengths, or 60, 60, and 30, respectively. Now simply calculate 60 + 60 - 30 = 90.</p>
<p>1.7.16. g(x) = k(x + 3)(x - 3) has its zeroes at -3 and 3 as you can verify from the graph. g(a - 1.2) = 0 implies that a - 1.2 is one of the zeros of g(x), and this gives a = -2 or 4.2. Since a > 0, a = 4.2.</p>
<p>2.2.10. Triangle PQT and PRS are similar (AA). Then it follows that PT/PS = QT/RS = 8/10 = 4/5.</p>
