Answer:
15
Step-by-step explanation:
You can solve this by solving the equation given for x, this will tell you the range of numbers that would make the inequality true.
7x + 1 >= 8
7x >= 8-1
7x >= 7
x >= 7/7
x >= 1
So, x would have to be greater than or equal to 1. Given the set of numbers in the problem; the numbers 1, 3, 6 would satisfy the inequality. The answer is (A).
(2n^2 + 4n + 4)(4n − 5)
=(2n^2 + 4n + 4)(4n + −5)
=(2n^2)(4n) + (2n^2)(−5) + (4n)(4n) + (4n)(−5) + (4)(4n) + (4)(−5)
=8n^3 − 10n^2 + 16n^2 − 20n + 16n − 20
=8n^3 + 6n^2 − 4n − 20
Answer:
Step-by-step explanation:
look, area = length x width
so that means that the area of this rectangle is
= 11 1/2 * 8
= 23/2 * 8
= 23 * 4 (simplified)
= 92 in^2
