The answer would be 11/2.

2d = 5 + 6 (add 6 to both sides)

2d = 11 (simplify 5 + 6 to 11)

d = 11/2 (divide both sides by 2)

Decimal form is 5.5.

What is the value of x so the rectangles have the same area.<br> a. 12 &amp; X<br> b. X-2 &amp; 16
Ilya [14]
The area of a rectangle is <em>L x W</em>. We have to get the value of x first so that we can find the area of the rectangle.

To get the value of x
given:
<span>a. 12 & X
b. X-2 & 16 </span>
solution:
12x (x) = (8-2 ) 16
12x = 16x-32
32 = 16x-- 12x
<u>32 </u> = <u>4x</u>
4        4
8 = x

Checking:

a. 12 & X                                                          b. X-2 & 16
Area of a rectangle = L x W                            Area of a rectangle  = L x W
                                =12 x 8                                                             =  (8-2) 16
Area of a rectangle = 96                                                                  = 6 (16)
                                                                        Area of a rectangle  = 96

JulsSmile [24]

There are two shapes a rectangle and a triangle.

Area of a rectangle = Length x width = 10 x 8 = 80 square ft.

Area of triangle = 1/2 x base x height = 1/2 x 6 x 8 = 24 square ft.

Total area = rectangle + triangle = 80 + 24 = 104 square ft.

Answer 104 square ft.

Annie says the two expressions are equalized. Is she correct? Explain using different strategies -3x+6 and 3(-x -2).
borishaifa [10]

Step-by-step explanation:

By using Distributive Property on 3(-x - 2),

3(-x - 2) = (3)(-x) + (3)(-2) = -3x - 6.

Since -3x - 6 =/= -3x + 6,

they are not equalized.
