N^2 +5n -1 evaluate the expression when n = -6

5

Step-by-step explanation:

substitute n=-6 into the expression

therefore, (-6)^2+5(-6)-1=36-30-1

=5

Step-by-step explanation:

1) N is equal to -6 and you are challenge to find the value in the expression n²+5n -1.

so we have:-

n= -6

the expression is n²+5n-1

2) next we substitute the value of n= -6 in the expression n²+5n-1. this means wherever we see 'n' in the expression, we replace it with '- 6 ' so instead of writing n we will write the value -6. thus we have:-

(-6)² + 5(-6) - 1

36+ (-30) - 1

36-30-1

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
