A=6a^2
A=6(5.5)^2
A=181.5
Hopefully I answered correctly.
Answer:
x = 30, x = 5 and x = 9
Step-by-step explanation:
The diagonals of a square are perpendicular bisectors of each other, so
∠ AEB = 90° , then
3x = 90 ( divide both sides by 3 )
x = 30
---------------------------------------------------------
(9)
The 4 angles of a square are right and the diagonals bisect the angles, then
∠ BAC = 45° , so
9x = 45 ( divide both sides by 9 )
x = 5
-------------------------------------------------------
(10)
All sides are congruent , so
CD = AB , that is
3x - 5 = 2x + 4 ( subtract 2x from both sides )
x - 5 = 4 ( add 5 to both sides )
x = 9
Answer:
-9
Step-by-step explanation:
18÷x = -2
18 = -2×x
18 = -2x
-9 = x
x = -9
5 (2.3) = 11.5
Hope this helps
The answer is C because there is 2/6 chance of rolling a 3 or 5. 2/6 times 260 = 86.6 which rounds up to 87
