Answer:

70 inches

Step-by-step explanation:

Finding the perimeter of a rectangle means taking two sides of the same length and adding them to two sides of a seperate length. 20 times two is 40, 180 minus 40 is 140, 140 divided by two is 70. Meaning that the length of the rectangle must be 70 for the width to be 20 and the perimeter to be at least 180 inches.

20x2 = 40 in width
180-40= 140
140/2=70

Can someone help me <br><br> 1.3x-338
Olegator [25]

Answer:

Equivalent expressions are expressions which are equal. This means they simplify to the same expression. Simplify the two expressions -1.3x - (-8.9x) = 7.6x and -1.3 + (-8.9X) = -10.2x.

Then simplify each option to determine if it is equal -1.3x - (-8.9x), -1.3 + (-8.9X) or neither:

−1.3x−8.9x  = -10.2x. This is equivalent to  -1.3 + (-8.9X) .

8.9x+(−1.3x)  = 7.6x This is equivalent to  -1.3x - (-8.9x) .

−8.9x+(−1.3x)  = -10.2x This is equivalent to  -1.3 + (-8.9X) .

8.9x−(−1.3x)  = 10.2x Neither

−1.3x+8.9x  = 7.6x This is equivalent to  -1.3x - (-8.9x)  .

−8.9x+1.3x = -7.6x Neither
