The first one is A. And Sowy but meh don't know the second one...
Answer:
Area = 1/2 b x h
18 = 1/2 ((x) x 4x)
18 =1/2 4x^2
36 = 4x^2
36/4 = x^2
9 = x ^2
x = 3
Base = 3 m
Height = 4 x base = 4 x 3 = 12 m
Step-by-step explanation:
Let the 4 integers be x, x+2 , x+4 , x+6 Then
4x + 12 = 7(x + 6)
4x + 12 = 7x + 42
3x = -30
x = -10
The integers are -10 -8 , -6, and -4 answer
The difference between a number and seven is less than zero.
Judging by the question I noticed that the two both share x^3 in common. You can divide x^4 by x^3 and get x as a result, and x^3 can still divide into itself.
Thus your answer should be C, x^3
