Answer:

B. 3 square feet

Step-by-step explanation:

The formula for surface area is:

2lw+2lh+2wh

Box F's surface area is just plugging in those variables

2(3)(3)+2(3)(3)+2(3)(3)=54

Box J's surface area is the same way

2(2)(4.5)+2(2)(3)+2(4.5)(3)=57

The difference is 57-54=3

The answer is B. 3 square ft

68, 72, 73, 76, 80, 90, 94, 94, 101, 112, 120

Median = 90
Lower Median = 73
Upper Median = 101

IQR = 101 - 73

Please help me<br> solve (x+3) (x+7)

vodka [1.7K]

Step-by-step explanation:

Here, we'll need to multiply these two values together. I'll use the expansion formula, which goes as follows:

$(a+b)(c+d)$

Expand

$ac + ad + bc + bd$

Lets apply this to the following equation:

$(x+3) (x+7)$

Expand.

$(x*x) + (x * 7) + (3 * x) + (3 * 7)$

Simplify.

$(x^2) + (7x) + (3x) + (21)$

Remove parenthesis and add.

$x^2+10x+21$

Answer:

x^2+10x+21
