Answer:
2x+5
Step-by-step explanation:
Formula for the perimeter of a reactangle= 2(l+b)
So,
2(l+b) = 10x+18
2(3x+4 + b) = 10x+18
Rearrange and solve
3x+4+b = 5x+9
b = 5x+9 - 3x - 4
b = 2x+5
Thus the measurement of the width = 2x+5
Hope this helps
Answer:
2437.5 Miles
Step-by-step explanation:
first find how many miles 1 inch is 625/5 = 125
next you multiply 19.5 * 125 = 2437.5 miles
Due to the Triangle Angle Sum Theorem, we know that the sum of the interior angles of a triangle is 180 degrees.
90 + 2x - 2 + x + 5 = 180 degrees.
Combine like terms.
3x + 93 = 180
Subtract 93 from both sides.
3x = 87
Divide both sides by 3
x = 29
Subtract 19 from both sides
-3x=2+x
Subtract x from both sides
-4x=2
Divide both sides by -4
x=-1/2
Final answer: x=-1/2
