Answer:
13x^2 - 7x + 6
Step-by-step explanation:
(9x^2 -7x) - 1(-4x^2 + 6)
(9x^2 -7x) + 4x^2 +6
9x^2 - 7x + 4x^2 + 6
(9x^2 + 4x^2) - 7x + 6
13x^2 - 7x + 6
Step-by-step explanation:
The probability that a farm has 500 or more acres is:
P = 0.076 + 0.047 + 0.035
P = 0.158
Answer:
A: -16/3
B: 16/3
C: -6
D: -6
E: 6
Step-by-step explanation:
A would be -16/3 because you multiply -2 time 8 which is 116. And the denominator is 3.
B would be 16/3. It is the same as problem A but there are two negatives which make positive.
C is -6. You just divide -18/3.
D is the exact same as C. It just has parenthesis but the answer is still -6.
E is 6 because there are two negatives which make a positive.
These are the answers. You subtract 6 from -3 giving you n≥-9. Since n/3 is a fraction, in order to undo it we must multiply it to the other side, giving us n≤-63.
1. n≥-9
3. n≤-63
