A.) 120

The variance is the range of a data set, which shows how spread out numbers are. To get the variance, we take the last number and subtract it from the first number. 160-40=120. Therefore, there is 120 numbers between 40 to 160.

2(2x + 4) + 2(x - 7) = 78. Determine the side lengths of this rectangle.

sp2606 [1]

$2(2x + 4) + 2(x - 7) = 78$

$4x + 8 + 2x - 14 = 78$

$(4x + 2x) + (8 - 14) = 78$

$6x - 6 = 78$

$6x = 78 + 6$

$6x = 84$

$x = \frac{84}{6}$

$x = 14$

Subtract 430 and 512 and turn into a percent
82%

Divide by 82%is11.487804
Skip a few times until u reach 11.48
Add 4+8 and then dvd:1 dvd to buy
So 4+8is12 plus 11 is 23 and one dvd it’s 24
So the answe is 24%
