Step-by-step explanation:
The man was warned not to use certain emojis in responding to messages.
ANSWER:
length=37
width=19
HOW TO DO IT:
perimeter = 2(l+w)
110=2(l+w)
l=2w+1
now plug that into the equation (substitution)
110=2((2w+1)+w)
110=2(3w+1)
110=6w+2
now solve for w
108=6w
w=18
now plug w into the equation again to solve for l
110=2(l+18)
110=2l+36
74=2l
l=37
<span>4|2x − 2| + 10 = 34
</span><span>4|2x − 2| + 10 - 10 = 34 - 10
</span><span>4|2x − 2| = 24
</span><span>|2x − 2| = 24/4 = 6
2x - 2 = 6 or 2x - 2 = -6
2x = 6 + 2 or 2x = -6 + 2
2x = 8 or 2x = -4
x = 8/2 or x = -4/2
x = 4 or x = -2
To check for extraneous solutions:
</span>For x = 4: <span>
4|2(4) − 2| + 10 = 34
4</span><span>|8 − 2| = 34 - 10 = 24
6 = 24/4 = 6 (solution is valid)
</span><span>For x = -2: <span>
4|2(-2) − 2| + 10 = 34
4</span><span>|-4 − 2| = 34 - 10 = 24
</span></span><span><span><span>|-6| = </span>6 = 24/4 = 6 (solution is valid) </span>
</span>
Therefore, solutions are x = 4 , x = -2
