Answer:
Multiply
3 by −
2
=−
6
x
Step-by-step explanation:
Answer: B. False
Step-by-step explanation: Because you do
4x - 3 = 19
+3 +3 =4x = 22
You divide 4x divide by 4 and you get x
Then you divide 22 by 4 and get 5.5
So the answer is X = 5.5
Answer: x-2
Step-by-step explanation:
Answer: A, 102
Step-by-step explanation:
Okay so just find the big square and subtract the holes
big square is 30x20 which is 600
hole #1 is 20x5 = 100
hole #2 is a triangle so you first find the base and height which are 10 and 5 respectively. Then use the triangle area formula a = 1/2bh to find that the triangle's area is 25.
Subtract the holes now
600-100-25 = 475
1 Gallon = 200 square feet covered so divide 475 by 200 to find how many gallons should be used. It's 3 gallons since you can't just buy a fraction of a gallon (Unless your being weird).
One gallon is 34, so 3 gallons is 3*34 = 102
Or in other words... A
hope you learned and can incorporate these methods for future problems :D!
Answer:
-
Step-by-step explanation:
-x= -1x. (The 1 is invisible)
Now lets do the 3*-1= -3
You still have both of the x's.
All you do is add them. 1+1=2
So, your exponent is going to be 2 with x attached
***When you are multiplying and you have the same exponent, add them. Pretend that you see the exponent 1 by the x (
) now since you have 2 (
) which equals (
)
Looks Like:
3x* -x
=3x* -(1)x
= 
Hope this helped :)
