To factor by grouping, you group up the 1st 2 terms together and the last 2 terms together and then factor those pieces.

(x^3 + x^2) + (x + 1)
x^2(x + 1) + 1(x +1) - now factor out the (x + 1)
(x + 1)(x^2 + 1) - final answer

if rhombus ABCD were reflected across the x axis to create rhombus A'B'C'D', what would the measure of angle D' be?​
Mrac [35]

Answer:

D.64

Step-by-step explanation:

A linear line equals up to 180

A+D=180

Substitute 116 for A

116+D=180

Subtract 116 from both sides

D=64

A reflection across the x-axis won't change the measure of an angle

The answer is 64.

Answer:

-The total area of a Rectangular Prism:

A = 366 in^{2}

Step-by-step explanation:

-To find the total area of a rectangular prism, you need this formula:

A = 2(l \cdot w +  l \cdot h + w \cdot h)

l = Length

w = Width

h = Height

-Apply the length, width and height for the formula:

A = 2(11 \cdot 8 +  11 \cdot 5 + 8 \cdot 5)

l = 11 in

w = 8 in

h = 5 in

-Then, solve for the area:

A = 2(11 \cdot 8 +  11 \cdot 5 + 8 \cdot 5)

A = 2(88 + 55 + 40)

A = 2(143 + 40)

A = 2 \times 183

A = 366

So, the total area would be 366 in ^{2}.
