Answer:
1. area = 1/2bh = (1/2)(21)(18) = 189 yd²
2. 3x2x3x2 = 36 different ways
3. area of kite = (1/2)(18)(24) = 216 units²
4. 8:52 or reduced, 2:13
5. Sorry, this is not my strong point
Step-by-step explanation:
Answer:
the answer is 12
Step-by-step explanation:
X = unknown number
10x - 16 = 2x
Subtract 10x from both sides to isolate the variable on the right side of the equation.
-16 = -8x
Divide both sides by -8 to get x alone.
2 = x

Answer: The polynomial
= y² - 5y - 4.
Step-by-step explanation:
Let the polynomial = f(y)
Therefore
y² -5y + 1 - f(y) = 5
f(y) = y² - 5y + 1 - 5
f(y) = y² - 5y - 4
The polynomial = y² - 5y - 4.
Check:
y² - 5y + 1 - ( y² - 5y - 4)
Open the bracket with the minus
y² - 5y + 1 - y² + 5y + 4
y² - y² - 5y + 5y + 1 + 4
= 0 - 0 + 5
= 5.
