3v-9v is -6v
-6v=30 Divide each side by -6
v=-5
To check: substitute -5 back into the equation wherever you see v
3(-5)-9(-5)=30
-15+45=30
30=30
We know, Perimeter of a rectangle = 2(l + w)
2(6+x+2) = 2(3+2x+1)
2(8+x) = 2(4+2x)
16+2x = 8+4x
16-8 = 4x - 2x
8 = 2x
x = 4
Unknown lengths, x+2 = 4+2 = 6
2x+1 = 2(4)+1 = 8+1 = 9
2) We know, Area of a rectangle = a * b
2[7(x+1)] = 4(3x+6)
2[7x+7] = 12x+24
14x+14 = 12x+24
14x-12x = 24-14
2x = 10
x = 5
Lengths of unknown sides, x+1 = 5+1 = 6 cm
3x+6 = 3(5)+6 = 15+6 = 21 cm
Hope this helps!
This means that she has 4 hours of free time since 25% is 1/4 and it said that 25% was 1 hour so you mush multiply 1 to 4 since it has 4 parts and 1 hour is only the 1st part.
Answer: the answer is C
Step-by-step explanation: we know this because a straight line is 180 degrees. So given 140 degrees we know that g= 40.
