Answer:
Step-by-step explanation:
Rectangle B :
P = 2(L + W)
L = 4
W = 6
P = 2(4 + 6).....P = 2(10)...P = 20 cm
so the perimeter of rectangle B is 20 cm
perimeter of rectangle A is 3 times bigger...
so perimeter of rectangle A is : (3 * 20) = 60 cm <==
=====================
another way to do this is if rectangle A is 3 times bigger, then the length and width are 3 times bigger too
so if rectangle B has a length of 4 cm, then rectangle A has a length of
(4 * 3) = 12 cm
and if rectangle B has a width of 6 cm, then rectangle A has a width of
(6 * 3) = 18 cm
so rectangle A perimeter is :
P = 2(L + W)
L = 12
W = 18
P = 2(12 + 18)...P = 2(30).....P = 60 cm <===
either way u choose to do it will give u the same answer

Answer: 17
Step-by-step explanation:
In this problem, the phrase "a number" can be interpreted as a variable. In this case, let the variable be "x."
Thus, "twice a number" = "2x"
"and 13" = "+ 13"
"is 47" = "= 47"
Thus, the problem is simply 2x + 13 = 47.
Then, simply subtract 13 from both sides to get 2x = 34.
Then, simply divide both sides by 2 to get x = 17.
Because "the number" is "x," the number is 17.
