You have to multiply the polynomials by each other:
(2x-1) * (5x-4) =10x^2-13x+4
(10x^2-13x+4)(x+4)=
10x^3+27x^2-48x+16
It is already in simplest form so you can’t refuse it or simplify it.
Answer:
A = 60 cm²
Step-by-step explanation:
Given that,
The area of a circle, A = 20 cm²
It is enlarged 3 times.
We need to find the area of the enlarged circle.
Area of the enlarged circle,
A = 20×3
= 60 cm²
So, the area of the enlarged circle is equal to 60 cm².
X=8+y
x+y=70
Rewrite the first equation to x-y=8
Copy the second equation x+y=70
Add the two equations and you get 2x=78
Therefore, x=39. Since this is the bigger number the smaller number(y) would have to be 31 because you subtract 8 from x which is 39. 39 is your answer.
