Answer:

(2*2*1.5*1/3)+(2*1.5*4)= 14

Step-by-step explanation:

To find the area of a pyramid, you use the equation of 1/3 *lwh. When we place the values in there, we get 2*2*1.5*1/3, which is equal to 2. Then we solve the bottom part. Since it is a rectangular prism, we use the equation of lwh. When we insert the values, we get 2*1.5*4, which is equal to 12. Now, we take these two values of 2 and 12 and we combine them, giving us our final answer of 14.

Im confused that's all - If 80% is 75 marks, what is full marks
never [62]

Let the full marks be represented by = x

As given, 80% of x is 75

So,

\frac{80}{100}*x=75

x= 80x=7500

x=93.75

Hence, full marks is 93.75

We can check also- \frac{80}{100}*93.75 =75

If f(x) = 4 – x2 and g(x) = 6x, which expression is equivalent to (9-1(3)?
Anni [7]

Answer:

( g − f ) ( 3 ) = 23

Step-by-step explanation:

(g-f)(x)=g(x)-f(x)

=6x-(4-X(2))

=x(2)+6x-4

to evaluate (g-f) (#) substitute x=3 into (g-f)(x)

(g-f)=(9)+(6 x 3) -4=23
