We have 2x + 2x + 32 = 256;
Then 4x + 32 = 256;
4x = 256-32;
4x = 224;
x = 224/4;
x = 56;
The width is 2·56 = 112 inches;
The length is 112 + 16 = 128 inches;
45+8.3 = 53.3
<span>45 - (2(8.3)) = 28.4
The value is </span> 28.4 <span>that is –2 standard deviations away from the mean.</span><span>

Step-by-step explanation:
Answer:
D. 49p² - 64
Step-by-step explanation:
(7p - 8)(7p + 8)
Solving this requires the 'difference of squares' concept which states;
If (a - b)(a + b)
Then the solution must be a² - b²
Considering (7p - 8)(7p + 8) then the answer is;
(7p)² - 8² = 49p² - 64
