To find the length of the missing side, subtract all of the known side from the perimeter.
14 + 19 + 25 = 58.
73 - 58 = 15.
The fourth side is 15 feet
I hope that helps!
Your answer should be x = 2, -2
I ran it through a very reliable program.
Answer:
A and C
Step-by-step explanation:
By letting x = 0 she is eliminating the terms in x , rather than simplifying
A
9x - 3x - 4 ← collect like terms
= 6x - 4
B
12x - 4 ← already in simplest form
C
5x + x - 4 ← collect like terms
= 6x - 4
Thus A and C are equivalent expressions
X= -4
y= 7
you can multiply the top equation by 3, then both y's are cancelled or zeroed out. You add -21 and 6 to get -15x. Than you add 42 and 18 to get 60. So, -15x=60 and from there you do 60/-15 to get x=-4. Plug in what you got for x into any of the two equations to get y, which is 7.
Where’s the image? There has to be an image showing the angles to see which pairs of angles are supplementary.
