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: w(10) = -12
Step-by-step explanation:
w(n) = -n - 2; Find w(10)
w(10) = -(10) - 2
w(10) = -10 - 2
w(10) = -12

Answer:
x = 2.4
Step-by-step explanation:
Given expression as,
2x - 4y when y = 3x - 6
Now put y in the given expression
so, 2x - 4 (3x - 6) = 0
2x - 12x + 24 = 0
10x = 24
So, x =
Hence, x = 2.4 Answer
