Answer:
A. The expression of "40 times the sum of 24 and 36" would be 40 x (24+36), and the value would be 2400.
B. for the words portion it would be "20 times the sum of 650 and 350", and the value of that expression is 20,000.
C. The expression of "divide the difference between 1,600 and 400 by 4" should be 1200 / 4, and if that is the correct way to format the expression then the value would be 300.
D. for the words portion it would be "100 times the sum of 78 and 12", and the value of that expression is 10,000.
Step-by-step explanation:
The diagram is a "mapping diagram" that describes a function? The function pairs numbers from the set on the left with numbers from the set on the right. "Domain" refers to the numbfers on the left, where the arrows come FROM. (Some people describe this as a mapping of x to y, with x on the left and y on the right.) The answer is B.
It should be the first one
Since both shapes are the same,we divide the total perimeter by 2. 80<span>÷2 is 40. Now that we have the perimeter of each individual shape we have to figure out the length of one side. Since all the sides are equal in length there is only 1 shape that has that - a square. A square has 4 sides so we need to divide 40 by 4 (because squares have 4 sides) and that equals to (40</span><span>÷4) 10cm on each side. Hope I helped!</span>
