The perimeter of a rectangle is all sides added up, so length + length + width + width.
L = length
W = width
then the perimeter is L+L+W+W, or 2L + 2W, or 2(L+W).
what's the length? well, is just
2(27).
All you have to do, is combine like terms. Let's go through it:
Arrange it so you can easily combine like terms:
So, your answer for the sum is 1) 7x² - 10x + 2
I have a simple but slightly time consuming way of doing this. Find 30% of 100 double it and then find 30% of 25, add the two together... In this case 60 + 7.5. After you do that subtract that number from 225. So subtract 67.5 from 225 and there is your answer. Your answer is 157.5
I would say the answer is A.
We know that:
48 roses costs $24
24 roses costs ?$
Step 1:
Use cross multiply
24×24=576
Last step:
Use division
576÷48=$12, so 24 roses costs $12. As a result, 24 roses costs $12. Hope it help!
