Solve: 90 is greater than or equal to -9(w+3)
Answers
another way
distributive propery
a(b+c)=ab+ac
90>-9(w+3)
distribute -9
-9(w+3)=-9w-27
now we have
90>-9w-27
add 27 to both sides
90+27>-9w+27-27
117>-9w
divide both sides by -9 and don't forget to flip relation symbol
-13<w
w>-13
any number from -13 and up is ossible

Answer:
Length of the door, l = 5 inches (in)
Width or Breadth of the door, w = 2 inches (in)
Perimeter p = 2(l + w)
= 2( 5 + 2) inches
= 2(5) inches + 2(4) inches
= 10 inches + 4 inches
= 14 inches or 14 in
Step-by-step explanation:
The perimeter of a plane shape is the measurement of the length of its outside boundary, which means the distance around its edges.
The door in the sketch is the shape of a rectangle. the distance around the edge of the door is the sum of all the sides. The longer side of a rectangle is called the length and it is usually represented by letter l while the shorter side is known as width or breadth represented by letter w and b respectively. The perimeter is calculated by the formula 2(l + w). where l means the length and w represents the width.
Final answer:
The perimeter of the door in the mural, when expressed in inches, is approximately 56.04 inches.
Explanation:
The subject of this problem is understanding scale drawings, a mathematical concept typically covered in middle school. To solve this problem, we first find out the actual dimensions of the door on the mural. In the sketch, 3 inches represent 1 foot. So, 1 inch would represent 1/3 of a foot. Hence, a door of 2 inches wide in the sketch would in reality be2/3 of a foot wide and 5 inches high in the sketch would be 5/3 of a foot high.
The perimeter of a rectangle (which is the shape of the door) is given by the formula 2 * (length + width). In terms of feet, the perimeter of the door in the mural would be 2 * ((5/3) + (2/3)) = 4.67 feet.
Since 1 foot equals 12 inches, the perimeter of the door in the mural would be 4.67*12, which equals 56.04 inches.
