The sum of two numbers is five more than twice the first. The sum of the number is 45. Find the numbers

First number is 20, second is 25

Step-by-step explanation:

x + y = 5 + 2x = 45

solve for x first

5 + 2x = 45

x = 20

then solve for y

20 + y = 45

y = 25

hope this helps

45

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
