Answer:

Step-by-step explanation:

"8 less than double a number is ten" can be converted into an algebraic equation.

-8 + 2x = 10

Then simplify.

2x = 18 (add 8 to both sides)

x = 9 (both sides divided by two)

Answer:

4 cm

Step-by-step explanation:

Both the area of a square and the area of a rectangle can be found by multiplying length x width. Because all of the sides of a square are equal, you get 64 when you multiply two sides together to find the area.

Since the rectangle has the same area as the square, that means the rectangle's width has to be a number that equals 64 when multiplied by 16.

So, 64/16 equals 4.

x = 26 m is the width of the pool, length: 29+4 = 33 m.

<u>Step-by-step explanation:</u>

We have A rectangular pool is surrounded by a walk 3 meters wide. The pool is 4 meters longer than its width. If the total area of the pool walk is 372 square meters more than the area of the pool.

Let the width of the pool = x

Then the length will = (x+4) ,over all dimensions will be (x+6) by (x+6+4) or (x+10)

Total area - pool area = 372

$(x+10)*(x+6) - x(x+4) = 372\\x^{2}+16x+60-x^{2}-4x = 372\\12x+60 = 372\\12x = 372-60\\12x = 312\\x = 26$

∴ x = 26 ft is the width of the pool, length: 29+4 = 33 ft
