Answer:
18 is the correct answer
Step-by-step explanation:
to find f(6) you only need to put value 6 in place x and then simple addotion subtraction
f(6)=4(6)-6
f(6)=24-6
f(6)=18
Answer:
252
Step-by-step explanation:
To answer the equation, you first need to note that it asks for surface area.
To find surface area, you use an input formula, known as <em>SA=2lw+2lh+2hw</em>. 'H' stands for height, 'L' stands for length, and 'W' stands for width.
Since the current height is 12, the current length is 6, and the width is 3, you need to plug them into the equation.
<em>SA=2(6)(3)+2(6)(12)+2(12)(3)</em>
<em>SA=252</em>
<em>Quick tip! It's tempting to just multiply them all at once, but using the power of distribution is vital to solving these equations. </em>
The answer would be:
ABD=78.8
DBC=61.1
The volume of a pyramid is V = 1/3 x base length^2 x height
Let X = base length.
We are told the height is 1/2 the length, so height would be 1/2x
Now we have:
972 = 1/3 * x^2 * 1/2x
Simplifying we get:
972 = 1/6x^3
Multiply both sides by 6:
5832 = x^3
Take the cube root of both sides:
x = 18
The length of the base is 18 inches.
The height is 1/2 that, so the height would be 18/2 = 9 inches.
