Hey! Your answer would be = 6ab+15ac
Answer:
n = (1/2)(-1 ± i√2)
Step-by-step explanation:
Among the several ways in which quadratic equations can be solved is the quadratic formula. Putting to use the coefficients {12, 12, 9}, we obtain the discriminant, b^2 - 4ac: 12^2 - 4(12)(9) = 144 - 432 = -288. The negative sign of this discriminant tells us that the quadratic has two unequal, complex roots. These roots are:
-b ± √(discriminant)
n = ---------------------------------
2a
Here we have:
-12 ± √(-288) -12 ± i√2√144 -12 ± i12√2
n = ---------------------- = ------------------------ = --------------------
2(12) 24 24
or:
n = (1/2)(-1 ± i√2)
the slope is the number that x is multiplied by so the answer is C)7
Your answer would be 13.5 cause each yard is 3 feet
Answer:
20 and 24
Step-by-step explanation:
You can write 5:6 as 5x:6x. You know that 5x+8=7x or that 6x+8=8x. You can solve either one and then you get x=4. Then you can plug it in. I hope this is helpful!
