Answer:
Step-by-step explanation:
let the width=x
length=3x+8
perimeter=2[3x+8+x]
=2[4x+8]
=8(x+2)
8(x+2)=64
x+2=64/8=8
x=8-2=6
width= 6 in
length=3(6)+8=26 in
Answer:
is it $12?
Step-by-step explanation:
62-50= $12
Answer:
Let's first find the slope.
-13 - (-8) / 2-1
-5/1
-5
The slope is -5.
The y intercept, or where the line crosses the y=axis, is equal to -3.
So, the equation is y=-5x-3

Step-by-step explanation:
enjoy your now nice study
Recall that:
sin(A + B) = sinAcosB + cosAsinB
Therefore:
sin11°cos19° + cos11°sin19° = sin(11° + 19°)
= sin30° = 0.5
I hope this explains it.
