(x+3)(5x-4)(2x-1)
multiply the first two by foil method
F x × 5x =5x²
O -4 × x =-4x
I 3 x 5x =15x
L 3 × -4 =-12
(5x²+11x-12)(2x-1) distribute
2x(5x²+11x-12)=10x³+22x²-24x
-1(5x²+11x-12)=-5x²-11x+12
combine like terms
10x³+22x²-5x²-24x-11x+12
Answer: 10x³+17x²-35x+12
Answer: 5/10 or 1/2
Step-by-step explanation:
Using it's concept, it is found that the coefficient of the mathematical expression 7m² + 2(19) is of 7.
<h3>What is the leading coefficient of a polynomial?</h3>
The leading coefficient of a polynomial is the <u>term that multiplies the highest exponent</u>.
In this problem, the expression is given by:
7m² + 19.
The highest exponent is of 2, in m², hence the leading coefficient is of 7.

So if we do 60,000*0.18=10,800 which is the number the price will decrease annually.
1=49,200
2=38,400
3=27,600
4=16,800
:D Hope this helps!
