B . side is a 8.5 inches long and side is 7 inches long
Answer:
1.) y=3x-7
2.) 2=5x-y
3.) y=-4-2x
4.) 1=3/4x+y
5.) y=4x+8
6.) 9=3/4x+8
7.) 9=y+x
8.) y=-2/6x+2
9.) 5=-2/3x+y
Step-by-step explanation:
Standard form is Ax=By=C and Slope form is y-mx+b
for all of the equations fiqure out which is standard and which is slope, 3x-y=7 is standard and just switch it to slope ie:
3x-y=7
+7 -7
3x-7=y
then switch around so y is in the front and vice versa, also divde any y or C by negative 1 if the answer is negative or if there is a number in front of it like in 9, and 8

Answer:
121.857
Step-by-step explanation:
6×7r = 5118
42r = 5118
r = 121.857
I think it's width= 3 times length
So the 1. length is 18/3=6
The 2. Width is 8*3=24
The 4. width is 12*3=36
