(x-7) (x+1)
Step-by-step explanation:
x^2 - 6x - 7
What two numbers multiply to -7 and add to -6
-7*1 = -7
-7+1 = -6
(x-7) (x+1)
2*y + 5*x < 2 hours But the units are not the same. The left side contains minutes and the right hours.
2y + 5x < 2*60
2y + 5x < 120 <<<<< Answer
Answer:
1.c

3.d
4.a
5.c
6.b
Step-by-step explanation:
sina=cos b
cosa= sin b
A=45
A=kx/y
where k is constant
substituting the values for k
k= 20×9/6=30
when x=9, y=6
A= 30×9/6=45
