Answer:
w = 5
Step-by-step explanation:
Given
- 4(w + 1) = - 24 ( divide both sides by - 4 )
w + 1 = 6 ( subtract 1 from both sides )
w = 5
The expression is rewritten in standard form and they are not the same due to the negative.
<h3>What is simplification of an expression?</h3>
Usually, simplification involves proceeding with the pending operations in the expression.
Simplification usually involves making the expression simple and easy to use later.
Both (x−3)(x+3) and (3−x)(3+x) contain a sum and a difference and have only 3 and x in each factor.
Let see the equation formed by the factor;
(x−3)(x+3)
= x^2 + 3x - 3x - 9
= x^2 - 9
(3−x)(3+x)
= 9 + 3x - 3x - x^2
= 9 - x^2
The expression is rewritten in standard form and they are not the same due to the negative.

Answer:
1974 mm^3
Step-by-step explanation:
The formula to find the volume of a rectangular prism/cuboid: l x w x h, where l is the length, w is the width and h is the height.
1) Input the values into the formula and solve it.
= 47 x 14 x 3
= 1974 mm^3

You need to find the circumference of the whole circular pool and then subtract from it the arc length that is 1/4 of the circumference. The circumference formula is C = (3.14)(d), which in our case is 3.14(40) which is 125.6. Now we need the arc length we need to take away. 1/4 of a circle corresponds to a 90 degree angle, so in the formula for arc length, we have this:
which equals 31.4. Now subtract that from the circumference of the whole circle and you get the outside of the circle minus that arc length. That's 94.2. But we have to go in the radius times 2 to enclose the pie shaped piece we cut away. So we have 134.2. She should've just stuck with enclosing the circle; she would have used less fencing!
