Answer:
(A) 4
Step-by-step explanation: The mean is all the numbers added divided by the amount of numbers. so 2 + 3+ 6 + 5 = 16 then you add the 4 that is 20 then divide 20 by 5 and if the answer is 4 its correct. The answer is 4 so its correct.
Answer:
the perimeter of the rectangle = 2(length + width)
= 2(4x^2 + 2 feet + 5x^2 + 3x feet )
= 2(4x^2 + 5x^2 + 2+ 3x)feet
= 2(x^2(4+5) + 2+ 3x) feet
= 2(9x^2 + 3x + 2)feet
= 18x^2 + 6x +4 feet
Step-by-step explanation:
The vertex is (-3,3),so a =-3, b=3. a+b=0
√x² - 4 + x²/x² + 1
x - 2 + x²/x² + 1
<u>x - 2</u> + <u> x² </u>
1 x² + 1
<u>(x - 2)(x² + 1)</u> +<u> x² </u>
(1)(x² + 1) x² + 1
<u>x³ + x - 2x² - 2</u> + <u> x² </u>
x² + 1 x² + 1
<u>x³ - 2x² + x² + x - 2</u>
x² + 1
<u>x³ - x² + x - 2</u>
x² + 1
x³ + x - 2
Answer:
35.5
Step-by-step explanation:
H, A
Cos=A/H
Cos 65= 15/x
x=15/cos 65
