A prime number is a number that has no other factors except 1 and itself. For example, the number 12 can be broken down into 1x12, 2x6, and 3x4, therefore 12 is not a prime number. However, the number 13 has no other factors except 1x13, therefore it IS a prime number. To answer this question, 19 and 19 could be used. Or 31 and 7. Or 33 and 5.

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:

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

Please help me solve this LCM

hodyreva [135]

Note that

$x^2 - y^2 = (x - y) (x + y)$

and

$x^2 + 2xy + y^2 = (x + y)^2$

Then their LCM is $\boxed{x + y}$ .
