A WRIGGLE.
a right triangle, a pentagon w/ a right angle, alot of shapes with right angles.
4 - w = 7 subtract 4 from each side 4 - 4 - W = 7 - 4 - W = 3 divide both sides by - 1 ( remember, the implied coefficient of w is - 1 ) (- 1/- 1)w = 3/- 1 w = - 3 =======check in original equation 4 - (- 3) = 7 4 + 3 = 7 7 = 7 ========checks
If you mean sqrt (3w +13) = sqrt(5w-7) with all terms under the radical, then just square both sides. then; 3w+13 = 5w-7 ( subtract 3w from each side ) 13 = 2w-7 ( add 7 to both sides ) 20 = 2w 10 = w
A shape w/ 11 sides is called a hendecagon.
A pentagon is a shape that has 5 sides.
A shape that has 10 sides (two dimensional) is called a decagon. A shape that has 10 faces (three dimensional) is call a decahedron.
for a 4 sided shape... w+w+L+L=perimeter perimeter is the outside of a shape. add all of the sides to get the perimeter.
A WRIGGLE.
w/2 - 18 = - 7 Add 18 to both sides of the equation w/2 = - 7 + 18 w/2 = 11 Multiply both sides by 2 w = 11 x 2 w = 22
The lengths of the sides of a shape with more than 3 sides does not provide enough information to determine its area.

the outside edge of a shape e.g if it was a square the formula would be P=(L)x(W)x2 or in simpler terms add up all the sides of the shape
L + W = P/2 = 18. In ratio of 7:2 sides are 7/9 x 18 and 2/9 x 18 ie 14 and 4
It's called surface area. The formulae vary depending on the shape. For example, a cube with a width of w has six sides, each of which has an area of w2, so the surface area of a cube is 6 x w2.
