Perimeter= 2l+2w
126= 2l+2w
l=2w
Substitute the value for l
126= 2(2w)+2w
126= 4w+2w
126=6w
21=w
Plug the value for w in to find l
l=2(21)
l=42
Final answer: Length-42 ft, Width-21 ft
Answer:
1. Given
2. Subtraction property of Equality
3. Division property of Equality
I hope I helped you^_^
Answer:
18
Step-by-step explanation:
4(3) -(-6)
4 times 3 is 12. When you subtract a negative number the negative number gets added so it would be 12 + 6 which is 18. Hope that helps :)
Answer: The simplified expression is: " -2y + 19 " .
________________________________
Explanation:
Simplify this given expression: " 10 - 6y + 4y + 9 " .
Start with combining the "like terms:
+ 10 + 9 = + 19 ;
- 6y + 4y = - 2y ;
Now write the simplified expression:
" -2y + 19 " .
Note that the variables come first; in order of degrees, then the numbers, if any.
Hope this helps!
Best of luck to you in the "Brainly community" and in your future academic pursuits!

1.7) < 7 and < 8 form a linear pair....which means, when added, they equal 180 degrees. So if < 7 = 61, then < 8 = (180 - 61) = 119 <=
1.8) angles that are supplementary will add up to 180. So if one of the angles is 38, then the other one is (180 - 38) = 142 <==
1.9) < 3 = < 5 (vertical angles are congruent)
1.10) < 2 = < 8 (vertical angles are congruent)
1.11) < 7 = < 1 (vertical angles)
1.12) < 6 = < 4 (vertical angles)
