Answer:
39
Step-by-step explanation:
-133/-7=19+15=39
check:39-15=19
19x(-7)=-133
Step-by-step explanation:
4x³ - 14x² + 12x
= 2x[2x² - 7x + 6]
= 2x[(2x-3)(x-2)]
= 2x(2x-3)(x-2)
Answer:
8 (x -9)
Step-by-step explanation:
I don't know if you ment 9 instead of 9, but if you did that that would be the answer!
Answer:
A = 73.33
B = 53.33
C = 53.33
Step-by-step explanation:
Mathematically, adding the 3 angles would equal 180
Thus;
A + B + C = 180 •••••(i)
Since B and C are congruent, that means they are equal ( we are looking at isosceles triangle)
B = C •••••••••(ii)
Lastly;
B = A -20 ••••••••(iii)
Make a substitution in equation 1;
A + A -20 + A -20 = 180
Since B = C ; C also is A-20
3A -40 = 180
3A = 220
A = 220/3 = 73.33
B = C = A -20 = 73.33 -20 = 53.33
