Answer:
Step-by-step explanation:
(g-f)(x) = 9x³ - 4x² + 10x - 55 - [ 4x³ +3x² - 5x + 20]
To remove the parenthesis, take - inside, multiply f(x) by -1
= 9x³ - 4x² + 10x - 55 - 4x³ - 3x² + 5x - 20
Now, bring like terms together,
= 9x³ - 4x³ - 4x² - 3x² + 10x + 5x - 55 - 20
= 5x³ - 7x² + 15x - 75
The answer is,

Also equivalent to about, 0.185188.
Answer:
x = 5/(a-b+3)
Step-by-step explanation:
ax+3x=bx+5
Collect all the terms that has x:
ax-bx+3x = 5 (Subtracting bx both sides)
Take out the x!
x(a-b+3) =5
Divide (a-b+3) both sides to solve for x
x = 5/(a-b+3)
Hope this helps!
Would really appreicate the brainliest!
Answer:
A) Reflection.
Step-by-step explanation:
From the figure shown, we can see that the blue triangle is flipped about the x-axis to form the red triangle.
When an object is flipped about a line, then this transformation is called reflection about that line.
Thus, we can say that reflection is taking place in the figure shown in which the x-axis is acting like a mirror. The blue triangle is the pre-image and the red triangle is the image after reflection.
The reflection about x-axis is given by:
We can check the co-ordinates of the triangles and confirm the the transformation occurring
Points of pre-image triangle:

Points of image triangle

Thus, the transformation is reflection.
Step-by-step explanation:
6 times 9 is 54.
54 divided by 2 is 27 volume ( recipitor) is 27 for no.1
6 times 7 is 42
42 divided by 2 is 21 is the recipitor or volume for no.2
there fore a has a bigger base surface
as base is measured by recipitorial angles
sorry if this isnt the right answer or what u wanted but I know it this way
