Answer: D
Step-by-step explanation: It said the grandparents were less than 89 years old, if it said that the grandparents that were 89 and younger had remembered that's when you would use a solid circle because the 89 would be included. But since 89 isn't included then it's an open circle.
No it is wrong
the product of it is
4x²+5x-6
so you have to multiply by 2
the naswer is 2(4x-3)(x+2)
The 1st number is x and the 2nd number is y:
x = 3y-4
3 + 2x - 2y = 11
The first equation says that x is equal to "3y - 4", so you can plug in "3y - 4" for x in the second equation:
3 + 2(3y - 4) - 2y = 11
3 + 6y - 8 - 2y = 11
-5 + 4y = 11
4y = 16
y = 4
Now that you have y, you can plug it into the 1st equation to get x:
x = 3y - 4
x = 3(4) - 4
x = 12 - 4
x = 8
So, the 1st number is 8 and the 2nd number is 4.
The answer to your question is -28
