Answer:(-1,-10)
Step-by-step explanation:
51T+9
51×T+9
These are the answers .. chose anyone because they both mean the same thing but the first one is more sophisticated
Let's see it...
-x+0+(-x)=0 ???
There is a + before the parenthesis, the sign is the same.
-x+0-x = 0
Since the x have equal sign, we add them to get -2x
We have 2x - 0 = 0
Move the zero to the right, so 2x = 0
Divide both for 2...
x = 0
Substitute 0 to x, so -0+0+(-0) = 0
0 = 0 the statement is true
Answer:
plug in 2 , answer is -1
Step-by-step explanation:
4-5= -1
Answer:
B : Length is 12, Width is 9
D: Area is 108
Step-by-step explanation:
Finding x:
Since the Perimeter is 42, subtract 14 from 42 to get 28. Then divide that by 4 to get 7. x = 7. Since x = 7 then 7 + 5 = 12. So the length is 12.
Figuring out the width:
When we find the perimeter we add all the sides, so 12 + 12 = 24 and 42 - 24 = 18. Divide 18 by 2 to get 9 and then add 12 + 12 + 9 + 9 just to check your answer
Since the you know the legnht and width, you now have to multiply them to fine the area. 12 x 9 = 108
