HELPP PLEASE
The diagram shows 3 identical circles inside a rectangle. Each circle touches the other two circles and the sides of a rectangle , as shown in the diagram.

The radius of each circle is 28mm

Work out the area of the rectangle .

Give your answer to 3 significant figures

Use the radius to find the length and width of the rectangle.

28×2= 56

56 is the diameter of each circle.

The Rectangle is 2 circles long so 56×2 is 112mm

that's the length of one side

but that's all I can figure out because the circles going up and down are overlapping so using the same method wouldn't work. I hope that gives you a little help

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
