Answer:
40x30= 1200, 20x15=300, 300/1200= 1/4.
Step-by-step explanation:
You can also visualize it. Imagine a field 40’ long and the boy cut the top 20’ of it but left 20’ of the bottom, he would have cut half of it at this point. Now it’s 30’ wide and he cut the left 15’ of what’s remaining but left the right 15’ uncut. So now there’s a 20’x15’ bottom right corner left uncut. There are 4 sections that are 20’x15’ and he left one out of four uncut, otherwise written as 1/4.
Answer:
10 + 8 + 10 + 10 + 10 + 10 + 8 + 8 + 6 + 6
Answer :
(x–30) (x-10)
Given equation :
• x² - 40x + A
when A = 300
1. Use the sum-product pattern
x²- 40x + 300
x²−10x−30x+300
2. Common factor from the two pairs
x² – 10x-30x+300
x(x−10)−30(x−10)
3. Rewrite in factored form
x(x−10)−30(x−10)
(x-30) (x-10)
