Answer:
10 and 19
Step-by-step explanation:
- In Algebra, an even number = 2x, because anything multiplied by 2 is even.
- There are two numbers in the question, I'll define the first one as 2x
- the other number is 1 less than twice of the first, so I'm going to define it <u>in algebra as 2(2x) - 1</u>, which is just 4x - 1
- the square of the first is
- the square of the second is
- add them together:
- this equation = 461, so
- simplify to
- I wont explain how to solve this here, since it is very complicated, if you don't know search up solving quadratics.
- the <u>solutions are 5 or -4.6</u>, it cannot be -4.6 since the question says positive, so the solution for <u>x = 5</u>
- substitute x into our equations for the two numbers in steps 1 and 2
- the <u>first number = 10, the second = 19</u>

Answer:
-3.4(2.7a-1.7)-1.2a= 47.3
A = -4
f(3) = 69
Step-by-step explanation:
Given f(x) =5x5 + 10x4 + 3x3 + 8x2 – 6x – 3; c = 3
f(x) = 25+40+9+16 - 6x - 3
f(x) = - 6x +90-3
f(x) = - 6f(3) = 69x + 87
Taken c = 3
f(c) = - 6c +90-3
f(c) = - 6c + 87
substitute c=3
f(3) = - 6 (3) +90-3
= -18 +87
= 69
Hence .,f(3) = 69
