What is the area of the composite figure?
lana [24]

Hello! :)

\large\boxed{A = 32.5cm^{2}}

We can use the following area to solve for the area of the trapezoid pictured:

A = \frac{1}{2}(b_{1} + b_{2})h

Where:

h = height

b1 = bottom base

b2 = top base

Plug in the given values:

A = \frac{1}{2}(9 + 4)(5)

Simplify:

A = \frac{1}{2}(65)\\\\A = 32.5 cm^{2}

A base ball diamond is square.The distance from home plate to first base is 90 feet.what is the distance from home plate to seco
Elena-2011 [213]

Because it is square, the distance from home to first base is the same as first base to second base.


Home to First is one side of a right triangle, first to second is the second side of the right triangle and then home to second base would be the hypotenuse of a right triangle.


Using the Pythagorean Theorem we can solve for the hypotenuse:

Let C = the hypotenuse:

90^2 + 90^2 = c^2

8100 + 8100 = c^2

16200 = c^2

c = √16200

c = 127.279 feet, round to 127 feet.

masha68 [24]

Answer:

x=2 or x=-2

Step-by-step explanation:

I'm not sure what you're asking, but when you solve, set both sets of parentheses equal to 0 and solve. This makes x either equal to 2 or -2.
