Answer:
The answer to your question is: letter C
Step-by-step explanation:
4x² + 5x - 6
Process
4 x - 6 = - 24
Find two numbers that added gives + 5 and multiply gives -24
These numbers are + 8 and - 3
4x² + 8x - 3x - 6
4x ( x + 2) - 3(x + 2)
(x + 2) (4x - 3)
Answer:
1.1-5.4=4.3
Step-by-step explanation:
because the total is 5.4 and the turtle was 1.1 up so subtract to see how much the turtle sank to the Bottom
Answer:
(7,12),(-12,-7)
Step-by-step explanation:
x^2 + y^2 = 193
x - y = - 5
x = y - 5
(y - 5)^2 + y^2 = 193
y^2 - 10y + 25 + y^2 = 193
2y^2 - 10y + 25 = 193
2y^2 - 10y + 25 - 193 = 0
2y^2 - 10y - 168 = 0
2*(y^2 - 5y - 84) = 0 This factors into
2*( y - 12) (y + 7) = 0
y = 12
in which case x = 12 - 5 = 7
y = - 7
in which case x = -7 - 5 = - 12
Number 4 would be: C
And number 5 would be: C
