Answer:
1 ≤ n
Step-by-step explanation:
7−3n ≤ n+3
+3n +3n
7 ≤ 4n+3
-3 -3
4 ≤ 4n
divide by 4 on each side
1 ≤ n

Answer:
C. 61
Step-by-step explanation:
Two sides are equal, so the triangle is an isosceles triangle.
Both base angles are equal.
Angles in a triangle add up to 180 degrees.
58 + x + x = 180
58 + 2x = 180
2x = 122
x = 61
Answer:
Option A.

Step-by-step explanation:
see the attached figure with letters to better understand the problem
In this problem we have a triangle with a circle inscribed in it
so

step 1
Find the length side B.C

substitute the given values

step 2
Find the length side C.D
Remember that

therefore

step 3
Find the length side E.D
we know that

substitute the given values

step 4
Find the length side E.F
Remember that

therefore

step 5
Find the length side A.F
Remember that

therefore

step 6
Find the perimeter


Our task here is to find possible factors of <span>x^2 + 27x + 162.
We need to check out possible factors of 162 first. Examples are:
2(81), 3(54), 6(27), 9(18), and so on. Notice that 9 and 18 add up to 27, so that the factors (x+9) and (x+18) produce x^2 + 27x + 162 when mult. together.</span>
