Answer:
x > 0.8
x > -2
Step-by-step explanation:
(x+6)(x+2)=60
expand
x^2+6x+2x+12=60
x^2+8x+12=60
minus 60 both sides
x^2+8x-48=0
factor
what multiplies to -48 and adds to 8
-4 and 12
(x-4)(x+12)=0
set each to zero
x-4=0
x=4
x+12=0
x=-12
x=4 or -12
solutions are x=-12 and 4
Answer:
₱445
Step-by-step explanation:
₱18.50(x)
x = number of pineapples purchased
₱18.50(80) = ₱1480
80 - 3 = 77
₱25.00(z)
z = number of pineapples resold.
25.00(77) = ₱1925
₱1925 = ₱1480 = ₱445
7,861 is one thousand (1,000) more than 6,861
6,861 + 1,000 = 7,861
Hope this helps

840 - 3/7(840) =
840 - 360 = 480
480 - 1/8(480) =
480 - 60 = 420
