Answer:
if you look at carefully the left triangle has two same side. so left-angle of C is 180-130=50 degree 5x+5x+50=180 x=13 degree
Step-by-step explanation:
for right triangle again one angle is 50 degree and other is 6*13-(3)=75 degree so 75+50+(10y+5)=180 degree y=5 degree
Answer:
x^4 + x^3 + 13x + 5
Step-by-step explanation:
Assuming you meant the x2 as x squared, then:
(11x+4)(11x-4)
