Vertical Angles Theorem: angles that are opposite each other and formed by two intersecting straight lines, are congruent.
6x - 7 = 4x + 7
2x = 14
x = 7
Or you can also do supplementary angles
6x - 7 + 20x + 5 = 180
26x - 2 = 180
26x = 182
x = 7
The answer is x = 7
5/12+5/12=10/12
10/12+10/12=20/12 wich =1.666666666666667theres ur answer to one.
dont know the answer to the other one
Sorry
Hope that helps
Answer:
A = 92y + 81
Step-by-step explanation:
Because A = number of attendees and if it adds 92 each year, you times the number of years by 92 and add 81 for the ones that were already there
This is an obtuse angle.
Obtuse is big and a show-off, acute is cute and shy and small. right angle is striaght angle up and right-down...
(3x²-2x-4)(2x²+x-3)=3x²(2x²+x-3)-2x(2x²+x-3)-4(2x²+x-3)=
=6x⁴+3x³-9x²-(4x³+2x²-6x)-(8x²+4x-12)=
=6x⁴+3x³-9x²-4x³-2x²+6x-8x²-4x+12=
=6x⁴-x³-x²+2x+12
