Fv=500×(1+0.04×3)+250×(1+0.04×2)+
250×(1+0.04×1)=560+270+260=1,090
X+15=102
102-15=x
x=87
Please give me brainliest
3 x 5 = 15
and now add the negative which is 3x-5= -15
Simplify:
6x + 6 = 3x - 15
Now use all solutions
6(7) + 6 = 3(7) - 15
42 + 6 = 21 - 15
Nearly, you can tell it doesn't work.
6(-7) + 6 = 3(-7) - 15
-42 + 6 = -21 - 15
-36 = -36
So, -7 is x.
The width and length could also be 8 and 2
