Answer:
y = 5
Step-by-step explanation:
All angle measures in a triangle add up to 180°.
- This means that 63 + 82 + 7y = 180
<u>Solving for Y:</u>
Step 1: Combine like terms.
Step 2: Subtract 145 from both sides.
Step 3: Divide both sides by 7.
Step 4: Check if solution is correct.
Therefore, y = 5.
Have a lovely rest of your day/night, and good luck with your assignments! ♡

Answer:
12 : 22
Step-by-step explanation:
Just as you look at it, the only factor common to all three terms is 'x'.
So you can factor the 'x' out and make the equation . . .
x (3x²-19x - 14) = 0
Right there, that tells you that [ x = 0 ] is a solution of the original equation.
But you're not looking for solutions, you're looking for factors, so you continue.
What about that ugly trinomial: [ 3x² - 19x - 14 ] ? Can that be factored ?
Not easily. But if you stuff it into the quadratic equation, you'll find two solutions
to the equation
3x² - 19x - 14 = 0
and you'll recall that (x - a solution) is a factor of the left side.
So you can find the remaining two factors of the original trinomial.
