Answer:
C
Step-by-step explanation:
The 10 inch sides will produce 10 / 3 = 3 squares and 1 inch left over.
The 18 inch sides will produce 18/3 = 6 squares with nothing left over.
The number of squares is 3 * 6 = 18
C
You have to find the percentage of calculators that are defective. to do this you do 6/900. Which equals 0.006666, you convert it to a percent by moving the decimal point 2 to the right which is 0.6666%, then you round to the nearest tenth as instructed in the question and you get 0.6%
Answer: If the x2-9 is x^2-9, then this is the answer. If not and it's supposed to be 2x then the answer is x=2 or x=−7 or x=9/2
Step-by-step explanation:
3(x−2)(x2−9)(x+7)=0
3x4+15x3−69x2−135x+378=0
Step 1: Factor left side of equation.
3(x−2)(x+3)(x−3)(x+7)=0
Step 2: Set factors equal to 0.
x−2=0 or x+3=0 or x−3=0 or x+7=0
x=2 or x=−3 or x=3 or x=−7
<h2>1.</h2>
So remember that with more than one pair of parentheses, you have to start from the inside and make your way outside.
Firstly, on the left side, solve 5+2 and on the right side solve 4 × 3:
![4[3(7)]=95-12](https://tex.z-dn.net/?f=4%5B3%287%29%5D%3D95-12)
Next, on the left side, solve 3 × 7 and on the right side solve the subtraction:
![4[21]=83](https://tex.z-dn.net/?f=4%5B21%5D%3D83)
Lastly, solve the remaining multiplication on the left side and the answer is 
<u>Since 84 is not equal to 83, the correct answer is the second option.</u>
<h2>2.</h2>
For this, plug 5 into the z variable to solve.

<u>Since 15 = 15 is true, your answer is the first option.</u>
<h2>3.</h2>
So for this, it's a similar process as Question 2 except that you are plugging in 0 into the x variable to solve:

<u>Since 8 = 0 is a false statement, the correct answer is the second option.</u>
