Answer:
(6x + 5)(7x² - 6)
Step-by-step explanation:
Factor the first/second and third/fourth term
42x³ + 35x² - 36x - 30
= 7x²(6x + 5) - 6(6x + 5) ← factor out (6x + 5) from each term
= (6x + 5)(7x² - 6)
CB = DA = √3*3+1*1 = √10
CD = BA = √2*2+1*1 = √5
Sum is 2√10 + 2√5 ≈ 10.8. So answer A.
Answer:
1+1=2 i think
Step-by-step explanation:
Answer:
x=10 5x=50 2x=20
Step-by-step explanation:
5x+2x+110=180
180-110=70
7x=70
x=10
5*10=50
2*10=20
