According to the feature of midsegment.:
LM =(AB + DC)/2
LM = 4x + 3.
AB= x + 8.
DC = 243.
<span>4x+3=(x+8+243)/2
</span>8x+6=x+251
7x=245
x=35 - the answer.
Answer & Step-by-step explanation:
The ratio of square feet to gallons of paint:
This can also be written as:
This fraction can be simplified by dividing the numerator and denominator by 6:
So, the ratio of square feet to gallons of paint is:
1 gallon for every 240 ft².

Answer:
x = 7
Step-by-step explanation:
The angle adjacent to the 70 degree angle is also 70 degrees. We assume that there are four 90-degree angles in the center of the figure. Thus, 8x - 36 + 70 + 90 = 180 (the sum of the interior angles is 180 degrees).
Solving 8x - 36 + 70 + 90 = 180 for x:
8x - 36 = 20, or 8x = 56.
Dividing both sides by 8 yields x = 7.
