if / means absolute value, then the answer is -3. The absolute value of 3 is 3, then you take the negative value of it, which is -3.
Btw, the absolute sign is ||, not //.
1) an = a1 + d*(n-1) => a20 = -4 + (-9)*19 = -4 - 171 = - 175
1) ---> C)
2) a81 = 20 + 4*80 = 340;
2) ---> A)
3) a12 = ?
3) ---> B) or D).
Answer:
Ellipse when the (tilted) plane intersects only one cone to form a bounded curve.
Step-by-step explanation:
hope it will help :)
Product of two consecutive integer so this mean that x and y but y = x+1 than
x(x+1)=1332
x^2 +x -1332 =0 so bc. you get 36*37=1332 and 37x-36x=x so you can rewriting this quadratic factorized completlie
x^2 +x -1332 = 0
(x+37)(x-36)=0
x+37=0
x=-37 so the larger integer result that will be 37
