Answer:

D -24/25

Step-by-step explanation:

sin(2x) = 2sin(x)cos(x)

cos(x) = ⅘

sin²(x) = 1 - cos²(x) = 1 - (⅘)²

sin²(x) = 9/25

sin(x) = -⅗

(Because 4th quadrant)

sin(2x) = 2(-⅗)(⅘)

= -24/25

Rachel is making a planter box. If her box measures 345 inches long and 543 inches wide, how many inches of board will she needs
dimaraw [331]

Rachel needs 1776 inches of board

<em><u>Solution:</u></em>

Given that, Rachel is making a planter box

Her box measures 345 inches long and 543 inches wide

Length = 345 inches

Width = 543 inches

<em><u>To find: Inches of board she needs</u></em>

So we need to find the perimeter of the board

The board is usually of rectangular shape

<em><u>Perimeter of rectangle is given as:</u></em>

Perimeter = 2(length + width)

Perimeter = 2(345 + 543)

Perimeter = 2(888)

Perimeter = 1776

Thus she needs 1776 inches of board

Consider the steps to simplify the expression. Which property is used to reach Step 3?
Stels [109]

NOTE: I ACCIDENTALLY clicked one star. That DOES NOT count as a real rating, and this DOES NOT mean my answer is bad!

Answer:

Commutative Property of Addition

Step-by-step explanation:

Step 2: -4 + (-37) + (-3) + (-47) + 7

Step 3: -4 + (-37) + (-47) + (-3) + 7

Because the order was changed, it is the Commutative Property.
