Answer: Half of a ton equals to 1,120 pounds.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
Since 80 stones make up half of a long ton, and each stone weight is 14 pounds, to obtain the number of pounds in half of a long ton we simply have to multiply the number of stones (80) by the weight of each stone (14)
Mathematically speaking:
<em>14 x 80 = 1,120 pounds
</em>
Half of a ton equals to 1,120 pounds.
There are 2 real solutions to the equation. Evaluate the discriminant = 8. Using the quadratic formula = What is on the picture.
Answer:
r^2 + 14r + 33
Step-by-step explanation:
Apply the "FOIL" method for multiplying two binomials:
(r+3) (r+11) = r^2 (first terms) +
+ 33 (last terms) +
+ 11r (outer terms) +
+ 3r (inner terms)
Combining ilke terms, we get:
r^2 + 14r + 33
