We can let the "a number" be represented by the variable x.
1) 7x
2) 7 + x
3) x - 7
4) 7 + 2x
Hope this helped and have a great day!

No, in order for this to be correct, you'd have to move BOTH decimals in the same direction the same amount of places.<span />

The rectangle with maximum area will actually be a square.

Each side will be of length 7/4 = 1 3/4.

Try to find the common factor which is 2.
So:
Multiply by 2 both variables in parenthesis and you get:
2*(l+w)

Answer:

Step-by-step explanation:

The diagonals of a rhombus are perpendicular, so ∠AED = 90° and ∠BEC = 90°.

∠DAE = 180° - ∠AED - ∠EDA = 180° - 90° - 35° = 55°

BD is a transversal across parallel sides AD and BC, so ∠EBC = ∠EDA = 35°.

∠BCE = 180° - ∠BEC - ∠EBC = 180° - 90° - 35° = 55°
