Answer:

f(x) + g(x) = x^2 + 4x + 35

Step-by-step explanation:

Add like terms from f(x) and g(x):

f(x) + g(x) = x^2 + 3x + 28 + x + 7, or

f(x) + g(x) = x^2 + 4x + 35

6 is added a number x.then the result is multiplied by 9. the final answer is greater than 99

drek231 [11]

So this inequality is going to be written as 9(x + 6) > 99

Firstly, you want to foil 9(x + 6), which will look like this: 9x + 54 > 99

Next, subtract 54 on both sides of the equation: 9x > 45

Lastly, divide both sides by 9, and your answer will be x > 5

The composite figure is made up of a triangular prism and a pyramid. The two solids have congruent bases. What is the volume of

Brums [2.3K]

The complete question in the attached figure

we know that
[volume of a cone]=[area of the base]*h/3
[area of the base]=22*10/2-------> 110 units²
h=19.5 units
[volume of a cone]=[110]*19.5/3------> 715 units³

[volume of a triangular prism]=[area of the base]*h
[area of the base]=110 units²
h=25 units
[volume of a a triangular prism]=[110]*25------------> 2750 units³

[volume of a the composite figure]=[volume of a cone]+[volume of a a triangular prism]
[volume of a the composite figure]=[715]+[2750]-------> 3465 units³

the answer is
The volume of a the composite figure is 3465 units³
