Answer:
Dimensions = 21 centimeters by 4.2 centimeters.
Step-by-step explanation:
Let the length of the rectangle be L.
Let the width of the rectangle be W.
Given the following data;
Perimeter of rectangle = 50cm
Translating the word problem into an algebraic expression, we have;
L = 5W
To find the dimensions of the rectangle;
Perimeter of rectangle = 2L + 2W
50 = 2L + 2W
50 = 2(5W) + 2W
50 = 10W + 2W
50 = 12W
W = 50/12
W = 4.2 cm.
To find the length;
L = 5W
L = 5*4.2
L = 21 cm.
Answer:
the answer is B) 12a+6b
Step-by-step explanation:
3+9=12 so 3a+9a=12a,
7-1=6 so 7b-(1)b=6b
Answer:

Estimating an angle measure in a problem can be useful when the actual angle measurement cannot be determined
<h3>When estimates are useful</h3>
Estimates are simply used to approximate and to guess the actual value of a measured quantity
In angles, when the actual measurement is not known, the estimate can be used in place of the actual value
Hence, estimating an angle measure can be useful when the actual angle measurement cannot be determined
