Our triangle is ABC with ∠C = 90°
1) AB² = BC² + AC² (Pythagorean theorem)
25² = 20² + AC²
AC² = 625 - 400
AC² = 225
AC = 15
2) PΔABC = AB + BC + AC = 25 + 15 + 20 = 60
3) SΔABC = AC * BC * 1/2 = 15 * 20 * 1/2 = 150
Answer: the perimeter is 60 cm and the area is 150 cm² .
Answer:
67.6
Step-by-step explanation:
Since 67.56 is 6 and above so, it is rounded to 6 so, it is 67.6.
Polynomial means more than 1 term when all like terms are combined
terms are seperated by plus or minus symbols
you can't combine placeholders and numbers
y is 1 term, not poly
4x^3+y is 2 term, poly
2+s is 2 term, poly
answer is 4x^3+y and 2+s
cubic means highest power of the placeholder is 3
quadratic means highest power of placeholder is 2
trinomial means 3 terms
yep, 3 terms
4x^2+3x+5
highest power is 2
quadratic trinomial
