Answer:
44.
Step-by-step explanation:
Since the mean of 14, 16, 16, 13, 23, x is 21, then we have 14 + 16 + 16 + 13 + 23 + x is equal to 126. Summing we have 14 + 16 + 16 + 13 + 23 = 82. 82 + x is equal to 126. X = 44.
84. Area of a triangle is (base x height) / 2
12! / 4!
= 1×2×3×4×5×6×7×8×9×10×11×12 / 1×2×3×4
= 5×6×7×8×9×10×11×12 = 19958400
Answer:
9
Step-by-step explanation:
Plug in -2 for x, and -1 for y, and solve:
3x - 4y + 11
3(-2) - 4(-1) + 11
Remember to follow PEMDAS. First, multiply. Remember, that when you multiply:
2 positive signs will result in a positive answer.
1 positive & 1 negative will result in a negative answer.
2 negative will result in a positive answer.
3 * -2 = -6
-4 * -1 = 4
-6 + 4 + 11 = 9
9 is your answer.

Answer:</h2><h2>Area of the kite = 80
, Area of traingle = 40
and height of the triangle, h = 5 cm</h2>
Step-by-step explanation:
A kite is broken into two triangles
Given the base of the traingle, b = 16 cm
Height of the triangle, h = 5 cm
Area of traingle = 
= 
= 40
Area of the kite = area of triangle 1 + area of triangle 2
= 40 + 40
= 80
