6m and 15m have a GCF of 3m, so divide both of them by 3m to simplify the fraction.

$\frac{6m/3m}{15m/3m}=\frac{2}{5}$

Find the area of the trapezoid. helppppopop thank you

Arada [10]

Answer:

$\frac{4}{3}\:\mathrm{cm^2}$

Step-by-step explanation:

The area of a trapezoid can be found by multiplying the average of its bases and its height.

We're given:

One base of 4 cm
One base of 12 cm
Height of 1/6 cm

To find the average of a set of $n$ values, add all the values in the set and divide by $n$ . Therefore, to find the average of the two bases, we add 4 to 12 and divide by 2.

The average of the bases is therefore $\frac{4+12}{2}=\frac{16}{2}=8$

Thus, the area of the trapezoid is $8\cdot \frac{1}{6}=\frac{8}{6}=\boxed{\frac{4}{3}\:\mathrm{cm^2}}$

Marta_Voda [28]

After substituting in what the symbols are really supposed to be it looks like this: 19-33/11+5*20. Use PEMDAS and plug it in to a calculator
NO parenthesis
NO exponents
Multiplication: 5*20=100
19-33/11+100
Division: -33/11= -3
19-3+100
Addition: -3+100= 97
19+97
ANSWER: 116
