3(x-2)+4(2x-3)
Use distributive property
3(x)-3(2)+4(2x)-4(3)
=3x-6+8x-12
Combining like term
3x+8x-6-12
=11x-18. As a result, 11x-18 is another expression that equivalent for 3(x-2)+4(2x-3). Hope it help!
CAB=17 degrees
CAB is the first section to the left. Point A is the center of your measurer, and the C and B are the end points of the angle. To find out the measure of angle CAB, you count the marks made in black between C and B, which results in 17 degrees—three less than the long mark at 20.

input. Find the input when the output is 15.
find out u
Answer:
Step-by-step explanation:
The quadratic expression in the standard form is given by :
f(x) = 
+ bx + c
(b) To complete the square:
Divide the equation through by a , the equation then becomes
f(x)= 
+ 
+ 
At this point, you are require to
(i) multiply the coefficient of x by 1/2
(ii) square the result
(iii) add the result to both sides , we have
f(x) = + + 
+ + by completing the square , we have
f(x) = 
+ - 
. We did this in order to make the expression balance
(c) Using the order of operation to turn the expression back into standard form
i. Expand the function in the bracket , we have
f(x) = + + 
+ -
⇒ f(x) = + + + -
⇒f(x) = + +
multiply through by the L.C.M , which is a , then we have
f(x) = - bx + c .
Since the aim of completing the square is to make the expression a perfect square , then it will always result in a perfect square trinomial.
