Hey there!
12 - 3 > 9
Rewrite the equation: -3x + 12 > 9
SUBTRACT by 12 on your sides
-3x + 12 - 12 > 9 - 12
Cancel out: 12 - 12 because it gives you 0
Keep: 9 - 12 because it helps us solve for our equation
9 - 12 = -3
New equation: -3x > -3
DIVIDE by -3 on your sides
-3x/3 > -3/-3
Cancel out: -3x/-3 because it doesn't give us what's being compared to the x
Keep: -3/-3 because it gives us our answer
-3/-3 = -3 ÷ -3 = 1
Thus your answer is: x < 1
Good luck on your assignment and enjoy your day!

nobody can answer this without the figure
brainly.com/question/2530631 Hey its me again. I answered this question of yours and coincidentally I found you again. ^-^
The first shape seems to be scaling up. From 3cm to 12cm. So for this you need to multiply. Using the formula that I gave you last time. 3cm times ___ = 12cm. 4 fits in there, therefore 6cm^2 times 4 = 24cm^2.
The answer for the first one would be 24cm^2. "24" in the blank.
The second shape seems to be scaling down. From 16cm to 8cm. So for this you need to divide. 16cm divided by ___ = 8cm. 2 fits in there, therefore 40cm^2 divided 2 = 20cm^2.
The answer for the second one would be 20cm^2. "20" in the blank.
The third shape seems to be scaling up. From 3cm to 4.5cm. So for this you need to multiply. 3cm times ___ = 4.5cm. Now since we're dealing with decimals, not whole numbers this time you can't really use guess and check as efficiently. So you do the opposite operation, which in this case the opposite of multiplication is division. You take 3cm (the original shape's number) and divide it into 4.5cm. So 4.5cm divided by 3cm = 1.5. 1.5 fits in there, therefore 20cm^2 times 1.5 = 30cm^2.
The answer for the third one would be 30cm^2. "30" in the blank.
Step-by-step explanation:
radius(CE)=diameter/2=9
EF=8inch
DE=8/2=4inch
pythagorean theorem:
im right triangle,
a^2+b^2=c^2
4^2+b^2=9^2
16+b^2=81
b^2=81-16
b^2=65
b=√65
√65≈8.06
