Answer:
b)
Step-by-step explanation:
n²+n-42=0
Using mid-term break
n²+7n-6n-42=0
n(n+7)-6(n+7)=0
(n-6)(n+7)=0
Either,
n-6=0 OR n+7=0
n=6 OR n= -7
Answer:
1
Depends on the cross section axis
place a cylinder can on a table , circular and side down .Look down at it and you see the other end so the cross section is circle
Turn it on its side and the cross section is rectangle
Let 1st number be = x
Thus second number = x - 4
Now
(x) + (x - 4) = 72
2x - 4 = 72
2x = 76
x = 38
1st number is 38 thus 2nd number is (38 - 4) = 34
The answer would be B. Because the greater than/less than or equal to sign is always a colored in dot. And doing the math you’ll see that 5x < 20 and then you divide to get x < 4. Same with the other.
90-47=
43°
x is equal to the space between the y axis and the line
