Answer:

36 m²

Step-by-step explanation:

To answer this question you will need the equation to find the area of a trapezium:

$\frac{(a + b)}{c}$ × height

Substitute the figures into the equation:

$\frac{(6+12)}{2}$ × 4

6+12= 18

After substituting use BIDMAS/ PETMAS to solve

18÷2= 9

9×4= 36 m²

Write the sum of the numbers as the product of their gcf and another sum Problem: 30+54

omeli [17]

The correct answer here is that the sum has to be 84. This is due to the fact that 30 + 54 is 84, and the greatest common factor is 6 because the factors of 30 are 1, 2, 3, 5, 6 , 10, 15, and 54's Factors: 1, 2, 3, 6, 9, 18, 27, and 54, so from this we can see that 6 is the great common factor.

Answer:

$g(x)=x-1\\g(f(x))=(-2x-5)-1\\g(f(x)=-2x-6$

Step-by-step explanation:

So this is a composition of functions. Think back to solutions of equations. You would have to put the equation into the other equations. It's like this!

So I graphed it like this on desmos:

$g(x)=x-1\\g(f(x))=(-2x-5)-1\\g(f(x)=-2x-6$
