Given that f(x) = 3x^2 + 5, we have

f(x + 3) = 3 (x + 3)^2 + 5 \\\\= 3 (x^2 + 6x + 9) + 5 \\\\= 3x^2 + 18x + 32

so that

f(x+3) - (f(x) + 3) = (3x^2 + 18x + 32) - (3x^2 + 8) \\\\= \boxed{18x + 24}

I don't know which one is the correct answer? PLEASE HELP!!​

The answer is 1/q^30 because after simplifying, you can cancel out the p and then you get q^q-20 times q^-10 to get q^-30 which then equals 1/q^30

Some help please stuck on 4, 8, 9

4:
a) if a cloud is a mid-level cloud, then it is between 6,500 and 20,000 feet.
b) if a cloud isn't a mid level cloud, then it is not between 6,500 and 20,000 feet. [I don't know if this statement is true]
8:
P=2l+2w
solve for w means to make the equation like w=... (get w on one side by itself).
First, subtract 2l from both sides
P-2l=2w
Now, divide both sides by 2
{P-2l}{2} = W
Done

*The question is a bit wrong here; it should have said In the corner of the angle ABC there is a little square symbol - that means it is a 90 degree angle.
The angle ABC is broken up into angles ABD and DBC, so ABD and DBC add up to 90 degrees.
So, we can make the equation (2x + 10) + (x + 14) = 90
Then solve
Since it is all addition, the parentheses are unnecessary
2x + 10 + x + 14 = 90
Add all x terms together, and the numbers together
3x + 24 = 90
Subtract 24 from both sides
3x = 66
Divide both sides by 3
x = 22
Now, plug in this x value into the formulas for the two angles
ABD = 2(22) + 10 = 44+10 = 54 degrees
DBC = 22 + 14 = 36 degrees

Help please this is due soon

Answer:

the area is 5.25 and the perimeter is 14

Step-by-step explanation:

first multiply 6cm and 1 3/4 which converts to 1.75, so 6x1.75+10.5 and to find the area of a triangle you multiply the base by the height and divide by 2 so 10.5 divided by 2 is 5.25 for the area, the perimeter is 14 because you're supposed to add all the sides and the sum is the perimeter 20 6 and 1/4 is converted to 6.25 therefore you add 6.25,6, 1.75 together to get 14
