Answer:
m = 4.25, or 17/4.
Step-by-step explanation:
Given the proportion:
Cross multiply:
8(m - 3) = 5 · 2
Distribute the 8:
8m - 8(3) = 10
8m - 24 = 10
Add 24 to both sides:
8m = 34
Divide both sides by 8:
8m/8 = 34/8
m = 4.25, or 17/4.
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)
