Try this: Combine 6 and 9, obtaining 15.

Compare this sum, 15, to the length of the 3rd side: 15.


If placed end to end, the 2 sides with lengths 6 and 9 form a new line of length 15. We'd end up with this new line superimposed on the 3rd side (with length 15).


Think: Do 2 straight lines of length 15, superimposed on one another, form a triangle?

Answer: 6.4cm

Step-by-step explanation:

The area of a trapezoid is given as:

= 1/2(a + b)h

We then slot the given values into the formula. This will be:

1/2(15.8 + b) × 7.3 = 81.03.

7.3(15.8 + b)= 81.03 × 2

7.3(15.8 + b) = 162.06

115.34 + 7.3b = 162.06

7.3b = 162.06 - 115.34

7.3b = 46.72

b = 46.72/7.3

b = 6.4

Therefore, the answer is 6.4cm.

Given f(x)= 3x+2, what is the Inverse Function?
Grace [21]

Answer:

Step-by-step explanation:

For this case we must determine the inverse of the following function:

f(x)=3x-2

Step 1:

We would write

y=f(x) or y=3x-2

Step 2:

We clear x:

y+2=3x

\frac{y+2}{3}=x

Step 3:

"x" and "y" are exchanged:

y=\frac{x+2}{3}

The inverse is:

f^{-1}(x)=\frac{x+2}{3}
