Answer:
x= -7 x = -1
Step-by-step explanation:
x^2 + 8x + 7 = 0
Factor
What 2 numbers multiply to 7 and add to 8
7*1 = 7
7+1 = 8
(x+7)(x+1) =0
Using the zero product property
x+7 =0 x+1 = 0
x= -7 x = -1
Answer:
450 portugals
Step-by-step explanation:
in this question, we are tasked with calculating the number of portugals which are picked by the farmer
Firstly, let the number of portugals picked be p and the number of oranges picked be r.
Thus;
p + r = 600 ••••••••••(i)
Secondly there are 3 times as many oranges as there are portugals;
That would be;
3 * r = p
3r = p. •••••••••(ii)
substitute ii into i
3r + r = 600
4r = 600
r = 600/4
r = 150
P = 3r
p = 3 * 150 = 450
