Answer:
<h2>
Perimeter = 2x² + 16x + 6</h2><h2>
Area = 6 x² + ¹/₂x - 3</h2>
Step-by-step explanation:
The perimeter = a + b + c + d
= (6x + 4) + (2x² + 5x - 3) + (-3x - 6) + (8x + 11)
= 2x² + 16x + 6
The area = [(a + b) ÷ 2] h
= [((6x + 4) + (-3x - 6)) ÷ 2] (4x + 3)
= [(3x - 2) ÷ 2] (4x + 3)
= (³/₂x - 1) (4x + 3)
= 6 x² + ¹/₂x - 3
Answer:
40.5 Units
Step-by-step explanation:
The area of a kite is A = (d1d2) / 2, where d1 and d2 are the diagonals of the kite.
Since the kite is inscribed in the square, and the sides of the square are 9 units, the diagonals of the kite are both 9 units.
d1 = 9 units
d2 = 9 units
A = (9units * 9units) / 2
A = 81units² / 2
A = 40.5 units²
Answer:
-1 -9i, where a = -1 and b = -9
Step-by-step explanation:
1st step is to open up the brackets. Since there's a (-) in front of the second bracket, we have to multiply every term by -1, so positive becomes negative, negative becomes positive etc.
4-i-5-8i
Then we collect like terms.
-1 -9i
This is the answer. It looks wrong since the variables are 'positive' in a +bi, but you have to remember that a variable can be represented as a, but its actual value could be negative, in this case -1. This is the same with b, as b could be the same as -9.
This is an expression, so we can't multiply everything by -1 to make it 'look right'. You can only multiply by -1 or 'alter' the terms when the expression equates to something.
