Answer: 4
Step-by-step explanation:
4 x 4=16-12=4
8.61 to the nearest tenth is 8.6
Answer:
4 IS $1
8 IS $2
12 IS $3
16 IS $4
Step-by-step explanation:
On the coordinate plane it would be a number on the top left and point at a bottom number, the top left is the first number and on the bottom is the last number. Hope that helped!
With the facts you got here, you can make the following equation:
x*(x+2)=24
x^2+2x=24
x^2+2x-24=0
Then you can use the following formula (which you might have seen before):
x = (-b +/- sqrt(b^2-4ac))/2a
where
ax^2+bx+c=0
(-2 +/- sqrt(4+96))/2
(-2 +/- 10)/2
x_1 = 4
x_2 = -6
If you multiply or divide by a positive number the inequality sign DOES NOT CHANGE!
If you multiply or divide by a negative number the inequality sign flips around and becomes the opposite.
