The two angles form a right triangle which is 90 degrees.
Add the two to equal 90:
3x-8 + 4x = 90
simplify:
7x-8 = 90
Add 8 to both sides:
7x = 98
Divide both sides by 7:
x = 14
Answer:
-9
Step-by-step explanation:
-3 times -3 = -9.
That's the exact answer; they usually want a calculator approximation at this point,
Hello,
I am wondering if you posted the full question.
This is trivial because it is already factorised. 0 is the zero with multiplicity 2.
And the factor are x.
Hope this helps.
Do not hesitate if you need further explanation.
Thank you
