Write and solve an equation to find the unknown side length x (in inches). Perimeter =24.2 in. Sides of the shape are 8.3, 8.3,

Anastasy [175]

Answer:

Perimeter of shape,which is a convex polygon i.e quadrilateral = 24.2 in

Sides are 8.3 in, 8.3 in, 3.8 in ,and length of fourth side be x in.

As , Perimeter = Sum of all sides

→ 24.2 = 8.3 + 8.3 + 3.8 + x

→ 24.2 = 16.6 +3.8 + x

→ 24.2 = 20 .4 + x

Keeping like terms on one side, of equation

→ 24.2 - 20.4 = x

→ 3.8 = x

→ x = 3.8

So, length of fourth side = 3.8 in

The given shape is definately either a Parallelogram or a kite.

Please help me with both questions!

Answer:

maximum area will be 1058 square yards

maximum height will be 81 feet

Step-by-step explanation:

P = 2L +2W

but in this case it will be P= L+2W and P=92 yards

L+2W = 92

Solve for L , L = 92-2W

The area of rectangle A = L x W

Plug in L and simplify: A = (92-2W)W =92W -2W²

Plot in your calculator and look for maximum so when the width is 23 yards maximum area will be 1058 square yards.

Second problems is the maximum height of the rocket. Maximum will be at the vertex of the upside-down parabola.
