I am going to assume that x2 = x squared
So: X^2 + 3x -40
= (X+8)(X-5)=0
X+8 = 0
X= - 8
The other solution is X -5 = 0
X = 5
Therefore the solution set is {-8, 5}
Closest to 1/2, because 3.5 is half of 7
Answer:
-10x +25
Step-by-step explanation:
–5(2x – 5)
Distribute
-5 * 2x - (-5) * 5
-10x +25
Parallel line means they have the same slope
y = mx + b
where m = slope
y = -3 + 4
here the slope is negative 3
y = -3x + b
plug in (4, 8)
8 = -3(4) + b
b = 8 + 12
b = 20
The answer is y = -3x + 20
Answer:
4pi
Step-by-step explanation:
Area of a circle is pi (r^2)
Radius is 2, 2 squared is 4, 4 times pi is 4pi.
