Answer:
x=1, x=-6
Step-by-step explanation:
x^2+5x-6=0 can be reduced to (x+6)(x-1)=0
we now have x+6=0 and x-1=0
solve by subtracting 6 from each side in the first equation and adding 1 to each side in the second.
x=1, x=-6
Answer:
₱445
Step-by-step explanation:
₱18.50(x)
x = number of pineapples purchased

Hey there :)
Without using a calculator it is not hard to identify where it lies.
√88
Which are the perfect squares before and after √88 ?
√81 which is 9 and √100 which is 10
Therefore, √88 is between 9 and 10
In case you use a calculator, we can see that:
√88 = 9.38
9 < 9.38 < 10
Answer:
13x-9
Step-by-step explanation:
9×(x - 1)
9x - 9 +4x
collect like terms, 9x+4x=13x
