Answer:
convert 't' to be 8/12 or 2/3 or .6 repeating
Step-by-step explanation:
Hello!
You can make two equations based on what you know
let x stand for andy's age
let y stand for Jeff's age
x = 2 + y
5 + x + 5 + y = 40
Put x into the second equation
5 + (2 + y) + 5 + y = 40
Combine like terms
12 + 2y = 40
Subtract 12 from both sides
2y = 28
Divide both sides by 2
y = 14
Put y into the first equation
x = 2 + (14)
x = 16
Andy is 16 and Jeff is 14
Hope this helps!
To find the missing side of a triangle, you would use trigonometric ratios, such as sine, cosine, or tangent.
Sine = opposite side/hypotenuse
Cosine = adjacent side/hypotenuse
Tangent = opposite side/adjacent side
“/“ = divided by
I hope this helped! Good luck!
Answer:
6y^3 + 12y^2 - 12y - 4
Step-by-step explanation:
So, you would multiply each in first equation for the second equation, you will got:
= 6y^2 * 6y + 6y^2 * 2 - 2*6y - 2* 2
= 6y^3 + 12y^2 - 12y -4
This would be the final expression
Hope this help you :3
