Answer:
40 + 3x + 4 + 3x + 4 = 180
48+6x=180
48 - 48 + 6x = 180 -4 8
6x = 132
6x/6 = 132/6
x = 22
Step-by-step explanation:
1. since the triangle is isosceles, angles A and C will have the same measures, so to solve for x, you can add another 3x + 4 or you can multiply A by 2.
2. add like terms
3. subtract
4. divide to get x
Answer:
C) |–60 + 11| = |–49| = –49 units
Step-by-step explanation:
Answer:
a(4) = 15/4
Step-by-step explanation:
Here we're told that the first term is a(1) = 30 and that the common factor r = 1/2.
Thus, the geometric sequence formula specific to this case is
a(n) = 30(1/:2)^(n-1).
What is the fourth term? Let n = 4,
a(4) = 30(1/2)^(4-1), or a(4) = 30(1/2)^(3), or a(4) = 30(1/8) = 30/8, or, in reduced form,
a(4) = 15/4.
You multiply the perimeter of the base by the height of the prism to get the lateral are or. LA=pB*H Lateral Area=perimeter of Base times Height
